Where does the fragrance go for an engagement at home? At the arrival and along the indoor route guests walk, which for an engagement is usually the front door, the hall, the stairs, the room where bags and wraps are left, the washrooms, and the connected living and passage space where people stand with a drink before and after the ring exchange. It does not go into the food area, because most of what we experience as taste is smell and a register at a noticeable level around a catering table is mixed into the meal rather than sitting beside it. It does not go near the stage or the flower arrangements, which already carry tuberose and rose. It never goes into a puja room. And if part of the evening is on a terrace, a lawn or an open courtyard, that air cannot be scented at all, because outdoor air has no ceiling and is continuously replaced.
Do you need a machine for an engagement, or will reeds do? It depends entirely on whether you are scenting one room or a connected floor, and the arithmetic decides it rather than the guest list. Floor area times ceiling height gives cubic feet, and cubic feet divided by 35.3 gives cubic metres, so a 600 sq ft living room at a 10 ft ceiling is 6,000 cubic feet or about 170 cubic metres, an 800 sq ft space is about 227, a 1,200 sq ft connected ground floor is about 340 and 2,000 sq ft is about 566. Reeds from Rs 749 are genuinely right for one bedroom or a washroom and genuinely wrong for a whole floor with sixty people moving through it. One large enclosed room is honestly a Megh at Rs 3,499 with the water-based Hotel Collection from Rs 299. A connected entrance, living, dining and passage is where the SOSA Vaayu at Rs 11,999 belongs, waterless to approximately 1000 cubic metres with a Bluetooth app and timer and four hotel-inspired blends in the box.
See the Vaayu
Facts verified August 2026: The SOSA Vaayu (₹11,999) is a waterless cold-air nebulising machine covering approximately 1000m³, with Bluetooth app and timer scheduling. It ships with four hotel-inspired waterless blends included in the box, chosen as one of three bundles at purchase: Bundle A - Ritz-Carlton Inspired, Westin Inspired, St. Regis Inspired, 1 Hotels Inspired; Bundle B - Westin Inspired, Shangri-La Inspired, Four Seasons Inspired, Ritz-Carlton Inspired; Bundle C - St. Regis Inspired, W Hotels Inspired, 1 Hotels Inspired, Four Seasons Inspired. Format distinction: the Vaayu and the HVAC systems run waterless nebulising oil, while the separate SOSA Hotel Collection fragrance (15ml ₹299) is water-based and runs in the ultrasonic machines only - Boond (₹899), Sukoon (₹1,899) and Megh (₹3,499). The two fragrance formats are not interchangeable, and the Hotel Collection bottle does not go into a Vaayu. SOSA Aangan (₹25,999) and SOSA Meenar (₹38,500) are HVAC nebulising systems for approximately 8,000-10,000 sq ft and 12,000-18,000 sq ft respectively, ducted into central air-conditioning. Reed diffusers need no power and make no noise: Morning Freshness ₹749, Garden Bloom ₹799, Evening Calm ₹799, Mountain Breeze ₹849, Fresh Brew ₹849; 130ml from ₹1,249; duo sets ₹1,498, ₹1,548 and ₹1,598. Scent perception is personal and varies between people in the same room, and coverage figures assume connected air volume rather than a partitioned floor plan. Ventilation, cleaning and air-conditioning come first; fragrance is an addition to a well-kept home and never a substitute for any of them. SOSA blends are SOSA's own hotel-inspired interpretations; SOSA is an independent Indian fragrance house and is not affiliated with, endorsed by or connected to any hotel brand. Made in India, cruelty-free and vegan. A portion of every order supports girl-child education through Nanhi Kali. Ongoing fragrance supply is arranged with SOSA on WhatsApp: +91 96192 18531.

Of all the functions a family hosts at home before a wedding, the engagement is the one where fragrance genuinely earns its place, and it is worth saying why rather than just saying so. A roka is one small room in the afternoon. A mehendi and a haldi are daytime, half-outdoors, and carry enormous smells of their own that fragrance should never be competing with. An engagement is usually indoors, usually after dark, usually across the connected volume of a ground floor, and usually the dressiest evening of the lot. That is a room a register can actually live in. It still comes with a limit and a hard safety rule, and both are on this page.
Quick answers — read this first
What fragrance should I use for an engagement ceremony at home? Something clean and composed, run gently across the connected indoor volume, with the warmer end of the range available to you because this is an evening function. The safest picks from SOSA's seven hotel-inspired registers are the Ritz-Carlton-inspired white tea, bergamot and cedar and the Westin-inspired white tea, aloe and cedar, both of which are quiet enough that nobody in a mixed family crowd will object. The Four Seasons-inspired citrus, floral and sandalwood is the polished, sociable option and sits well in a dressed-up room. The St. Regis-inspired amber, violet and woods is the plush evening register and an engagement after dark is the one home wedding function where it is genuinely right, though it reads as more present in a room than an airy white tea does, so it wants a bigger or better ventilated space and a lighter hand. Four of the seven come in the box with the SOSA Vaayu at Rs 11,999. SOSA blends are SOSA's own hotel-inspired interpretations and SOSA is not affiliated with any hotel brand.Where does the fragrance go for an engagement at home?

The short answer
Short answer: An engagement is the most scentable of the home wedding functions and it is worth saying why: it is usually indoors, usually after dark, and usually spread across a connected ground floor rather than crammed into one room. That is a volume a register can live in, unlike a mehendi or a haldi, which are daytime, half-outdoors and already carry enormous smells of their own. Scent the arrival and the indoor route: the front door, the hall, the stairs, the room where bags and wraps are left, the washrooms, and the connected living and passage space. Leave the catering area to the food and leave the stage and the flowers alone, because tuberose and rose are already doing that work. Never scent a puja room and never place a diffuser near a lamp or diya. If part of the evening is on a terrace or lawn, that air cannot be scented at all. Sizing is arithmetic, not guest count: floor area times ceiling height gives cubic feet, divided by 35.3 gives cubic metres, so 600 sq ft at 10 ft is about 170 cubic metres, 800 sq ft about 227, 1,200 sq ft about 340 and 2,000 sq ft about 566, against the SOSA Vaayu at Rs 11,999 rated to approximately 1000 as one connected volume. One large enclosed room is a Megh at Rs 3,499 with the water-based Hotel Collection from Rs 299; closed bedrooms and washrooms take a reed from Rs 749 each. Register: Ritz-Carlton-inspired or Westin-inspired white tea as the safe picks, Four Seasons-inspired citrus, floral and sandalwood for a polished room, St. Regis-inspired amber, violet and woods as the evening option with a lighter hand. Guests did not choose it and cannot leave, so dose gently. WhatsApp +91 96192 18531.

In this guide
A villa is not one room, it is a set of connected volumes and a set of closed doors, and the two need different answers. Whole-home scenting means one fragrance held evenly across the part of the house you actually live in - the entrance, the living room, the dining - running on a schedule so it is already there when someone walks through your front door, and already there when you come home yourself. The bedrooms, the guest bathroom and the study get their own quiet solutions. Nobody in the house has to remember anything.

Straight answer
Why is an engagement the one home wedding function worth scenting properly, and how do you actually do it?
Because it is indoors, after dark, and spread across a connected volume - and none of the other functions are all three. 1. Establish what you are scenting. Walk the route a guest takes: front door, hall, the stairs if there are any, the room where bags and wraps are dropped, the washrooms, and the connected living and passage space where people stand before and after the ring exchange. That route is the job. Multiply its floor area by the ceiling height for cubic feet and divide by 35.3 for cubic metres: 600 sq ft at 10 ft = 6,000 cu ft = about 170m³; 800 sq ft = 8,000 cu ft = about 227m³; 1,200 sq ft = 12,000 cu ft = about 340m³; 2,000 sq ft = 20,000 cu ft = about 566m³. 2. Match the machine to the volume, not to the guest list. A connected entrance, living, dining and passage is the SOSA Vaayu at ₹11,999 - waterless cold-air to approximately 1000m³, Bluetooth app and timer, four hotel-inspired blends in the box. One large enclosed room on its own is honestly a Megh at ₹3,499 with the water-based Hotel Collection from ₹299, and a smaller one a Sukoon at ₹1,899. Closed rooms and washrooms take a reed from ₹749 each, because no machine pushes scent through a shut door. 3. Choose for the evening. Ritz-Carlton-inspired white tea, bergamot and cedar or Westin-inspired white tea, aloe and cedar are the quiet safe picks; Four Seasons-inspired citrus, floral and sandalwood is polished and sociable; St. Regis-inspired amber, violet and woods is the plush evening register and this is the one function where it fits - with a lighter hand, because a warmer register reads as more present than an airy one. 4. Leave three things alone. The catering area, because food is the point and most of taste is smell. The stage and the flower arrangements, which already carry tuberose and rose. The puja room, entirely. And never place any diffuser near a lamp or diya. 5. Accept the outdoor limit. A terrace, lawn or open courtyard cannot be scented, because outdoor air has no ceiling and is continuously renewed. Put fresh flowers where people walk instead and spend your fragrance budget on the indoor arrival. WhatsApp +91 96192 18531.

The one wedding function that is genuinely scentable
Why this function is different from the others in the section, how to size the indoor route honestly, and where the warm end of the range finally becomes usable.
1
Why this one is different
Indoors, after dark, and one connected volume
It is worth being precise about what makes an engagement different, because the rest of this section says no rather more often than yes and you should be able to tell when the yes is real. It is indoors. Unlike a mehendi or a haldi, which drift out into a courtyard, a terrace or a lawn as soon as the sun allows, an engagement is usually held in the drawing room and dining and hall, with the doors shut and the air-conditioning on. Enclosed air is the only kind that can be scented at all, because a coverage rating in cubic metres describes one bounded connected volume; outdoor air has no ceiling and is continuously replaced, so it takes no fragrance from any machine. It is after dark. Evening air is cooler and calmer, people are not moving in and out to escape the sun, and the warmer registers that would feel heavy at two in the afternoon read as elegant at nine at night. And it is spread across a connected volume rather than crammed into one room. Guests arrive at the door, leave their things somewhere, stand with a drink, move through to where the rings are exchanged, use a washroom, come back for food. That is a route, and a route is exactly what a whole-home system is for: one register held evenly across entrance, living, dining and passage, so that the change at every doorway is nothing rather than a subject change. The other functions do not offer any of that. A roka is 85m³ of one room. A mehendi is a courtyard full of henna. A haldi is turmeric and marigold in the open air. An engagement is a hotel lobby problem in a house, which is the one shape this technology was designed around.
Tip: enclosed, evening and connected is the combination that makes scenting honest - and the engagement is the only function that has all three.

The sizing
Measure the route guests walk, then divide by 35.3
Sizing an engagement is arithmetic and it takes two minutes, and doing it is the difference between a purchase and a guess. Do not count the guest list; a crowd adds no cubic metres, it only warms the air and moves it faster. Count the connected volume instead: the part of the house that is genuinely open to itself on the night, which for most engagements is the entrance, the hall, the living room, the dining and the passage between them, plus the stair void if the staircase is open. Multiply the floor area by your ceiling height to get cubic feet, then divide by 35.3 for cubic metres. At a 10 ft ceiling: 600 sq ft = 6,000 cu ft = about 170m³; 800 sq ft = 8,000 cu ft = about 227m³; 1,200 sq ft = 12,000 cu ft = about 340m³; 1,500 sq ft = 15,000 cu ft = about 425m³; 2,000 sq ft = 20,000 cu ft = about 566m³. Two corrections that people routinely miss. Height eats coverage. A double-height entrance or drawing room is not a floor-plan number: a 600 sq ft room at a 20 ft ceiling is 12,000 cu ft, about 340m³ on its own, which is a great deal of air sitting in one room. Warm air rises, so in a double-height space place the unit low and let convection carry it up. Closed doors subtract. Whatever stays shut - bedrooms being used to get ready, the study, the store - is not part of the volume and not part of the machine's job. Now match. The SOSA Vaayu at ₹11,999 is rated to approximately 1000m³, which on paper is a connected ground floor of up to roughly 3,500 sq ft at a 10 ft ceiling, and it runs on a Bluetooth app and timer so the house scents itself while you are dressing. If your figure comes out at 150 or 200m³ and it is genuinely one enclosed room, a Megh at ₹3,499 with the water-based Hotel Collection from ₹299 is the better and much cheaper answer, and we would rather say that. For a large villa with genuine ducted central air-conditioning across every floor, the Aangan at ₹25,999 is the whole-home route.

The restraint
A dressed-up room is where over-scenting is easiest
An engagement is the evening people dress for, and that is precisely why it is the easiest of these functions to overdo. There is a temptation to make the house announce itself, and it produces the one failure everybody recognises: a hall that smells like a product rather than like a home. Four disciplines hold it in place. Start early and leave it alone. Run the schedule from the middle of the afternoon so the air is evenly scented rather than actively scenting when the first guest arrives, and then do not touch it for the rest of the night. Not at nine when you cannot smell anything, because you have been in the house all day and adapted hours ago. A level raised mid-evening is loud in the wrong place at the wrong moment and is still loud at midnight. Judge by the response, not the dial. Lovely house is a pass; what is that fragrance is a fail, however kindly it is meant, because it means the register has become an object in the room. Ask the first person through the door within thirty seconds, before their nose adapts too. Dose for the people who cannot leave. An engagement holds both families, which means grandparents, pregnant women, small children and at least one person prone to migraine, none of whom chose the scent and none of whom can step outside for three hours. Anyone reporting a headache is a recalibration signal rather than a difference of opinion, and the reduction should be permanent. Ventilation and cleaning come first and fragrance makes no health, therapeutic or air-purification claims. Keep one register everywhere. A different scent in each room reads as chaos rather than richness, and the doorway between two registers is where a guest notices something is off without knowing what. Run one across the connected volume and put the reeds from ₹749 behind the closed doors in the same family. And the absolutes stay absolute: nothing near a lamp or diya, and nothing in the puja room. Where the evening spills onto a terrace or lawn, that part is outside the system entirely - flowers do that job, not machines.
Tip: a dressed-up evening tempts you to turn it up - the sign of a well-scented engagement is that nobody can name the fragrance.
The SOSA principle
The engagement is the one home wedding function where a proper system is honest, because it is indoors, after dark and one connected volume - and it is still scented at the arrival, not at the stage.
Size the route by cubic metres, use the evening to unlock the warmer registers, and leave the food, the flowers and the puja room completely alone.

The SOSA home edit
Whatever the house looks like, the logic is the same: one scent, sized to the volume that is genuinely connected, running on a schedule so nobody in the family has to remember it. A single bedroom or a guest bathroom is happy on reeds with no power at all; the living room you actually live in wants a machine; the whole villa with central air-conditioning wants the ducts doing the work. Every SOSA system is made in India, cruelty-free and vegan, and a portion of every order supports girl-child education through Nanhi Kali. Here is where each one belongs.
The SOSA home edit
Where each one belongs in a house - one bedroom, one living room, or the whole villa
| System | Where in a home | Why it works there | Price |

| Reed diffusers (Morning Freshness ₹749, Garden Bloom ₹799) | One bedroom, a guest bathroom, a study | No power, no noise, no upkeep - alcohol-free reed oil and a few sticks. Evening Calm ₹799, Mountain Breeze ₹849, Fresh Brew ₹849; 130ml from ₹1,249; duo sets ₹1,498 / ₹1,548 / ₹1,598 | from ₹749 |
| Boond or Sukoon + Hotel Collection | A single room done properly | Water-based ultrasonic cold mist for one enclosed room - a bedroom, a home office, a puja room. Runs the water-based Hotel Collection only | ₹899 / ₹1,899 + ₹299 |
| Megh (6L) | A large living room or an open kitchen-dining | The 6L ultrasonic - long unattended runs through a whole evening on one fill, for the room you actually live in | ₹3,499 |
| SOSA Vaayu ★ | The connected living volume of a villa - entrance through living and dining | Waterless cold-air nebulising to ~1000m³, Bluetooth app and timer, and four hotel-inspired blends included in the box (choose Bundle A, B or C at purchase) | ₹11,999 |
| SOSA Aangan | Genuine whole-home coverage, approx 8,000-10,000 sq ft | HVAC nebulising, ducted into central air-conditioning - one signature in every room the ducts reach, including the floors above | ₹25,999 |
Honest notes before you buy anything. Coverage ratings assume connected air volume. A machine cannot push scent through a closed bedroom door, and it never will - so a partitioned villa is not one scenting problem but several, and honest sizing means saying so out loud rather than selling you one machine and hoping. Scent the volume that is genuinely open to itself, then give the closed rooms their own quiet answer, usually a reed diffuser. Fragrance never substitutes for ventilation or cleaning. If a room smells damp, stale or of last night's cooking, open it, air it and clean it first; scent added on top of that only makes a more complicated bad smell. A home is not a lobby you pass through. Households include children, elderly parents, pregnant family members and pets, all of whom breathe this air far longer than any visitor does, which is why gentle dosing is the default at home and why the settings we suggest are lower than the machine can run. Anyone in the house reporting a headache is a recalibration signal, not a complaint to argue with - turn it down or turn it off, and tell us. The Vaayu runs waterless nebulising oil and comes with the four hotel-inspired blends; the Hotel Collection bottle is water-based and belongs in the ultrasonic machines only. The two formats are not interchangeable. SOSA blends are SOSA's own hotel-inspired interpretations; SOSA is an independent Indian fragrance house, not affiliated with or endorsed by any hotel brand.

A note from Sonal
There is a difference between a room that smells nice and a home that has a signature, and almost nobody is told what it is. A room that smells nice is an event: you light a candle, you spray something in the hallway before people arrive, it is lovely for forty minutes and then it is gone. Somewhere else in the house a bathroom gel is doing one thing, a kitchen spray another, and a bedroom reed a third. Four pleasant smells in four rooms is not a fragranced home. It is four rooms.
A signature is the opposite. It is one scent, sized to the house, running on a schedule - so it is already in the air when someone walks through your front door, and already there at eleven at night when you come home yourself, and nobody has lifted a finger to make it happen. That is the whole trick the great hotels use, and it is not complicated: they do not chase smells room by room, they hold one fragrance across the volume people actually move through. In a villa that usually means the entrance, the living room and the dining as one connected space, with the closed rooms handled separately and quietly.
I trained at ISIPCA in Versailles and I have sized this for houses across India, and I would rather tell you honestly that your layout needs two answers than sell you one machine that disappoints you. Message us on WhatsApp at +91 96192 18531 with your home's approximate size, the number of floors and a line about the layout - open plan, closed rooms, central air-conditioning or split units - and we will give you a free sizing recommendation. I read those descriptions myself. Everything is made in India, cruelty-free and vegan, and a part of every order funds girl-child education through Nanhi Kali. Your home gets a memory; a girl gets a classroom.
Frequently asked questions
Is an engagement really more scentable than the other wedding functions?
Yes, and the reason is physical rather than a matter of taste. Scenting works on enclosed connected air, and an engagement is the only one of these functions that reliably gives you that. It is held indoors with the doors shut, it happens after dark when the air is calmer and cooler, and it spreads across a connected ground floor rather than being confined to one room, which is exactly the shape a whole-home system is designed around. Compare that with the rest of the section. A roka is one small drawing room in the afternoon, around 85 cubic metres, where a reed from Rs 749 is proportionate. A mehendi carries the strong, green, unmistakable smell of fresh henna, which is part of the occasion and should not be argued with. A haldi is turmeric paste and marigold, usually in a courtyard. And any function that moves outdoors is outside the reach of any machine, because outdoor air has no ceiling and is continuously renewed. So the yes here is a real yes, with the same limits attached: scent the arrival and the indoor route, and leave the ceremony and the food alone.
Should the room where the rings are exchanged be scented?
Scent the connected volume that room sits in, but do not treat that room as the target. The high-value moment for fragrance is the arrival, meaning the first breath a guest takes as they step in from outside air with a completely fresh nose, and that happens at the front door rather than in front of the stage. By the time people are gathered for the exchange they have been in the building for half an hour and have adapted to whatever is in the air, so a stronger level there buys you nothing and risks a great deal. There is also usually a large flower arrangement, often rose and tuberose, right where the ceremony happens, and those are strong, deliberate and correct for the occasion; a register competing with them at close range produces a muddle instead of a signature. Run one register gently across the whole connected space so the room reads as continuous with the rest of the house, put your effort into the entrance and the route, and let the flowers own the stage.
Can I use a stronger fragrance since it is a special evening?
It is the most tempting mistake on this page and the answer is no. Strength is not what makes a room feel expensive; consistency and restraint are, which is why the hotels people admire for this run one register at a low level everywhere rather than a loud one anywhere. There are also two practical problems with turning it up for the occasion. The first is that you are the worst judge in the building: you have been home all day and your nose stopped reporting hours ago, so the level that feels like nothing to you is the level a guest walks into. The second is that an engagement is a captive room. Both families are there for several hours, including grandparents, pregnant women, children and at least one person prone to migraine, and none of them chose your fragrance or can step out of it. Set it below where you think it should be, start it hours earlier instead, and if anyone mentions that the house smells strong, turn it down straight away and keep it down. A headache is information, not a complaint to argue with.
Half the engagement is on our terrace. What do we do about that air?
Nothing, and it is better to know that now than to buy hardware for it. Outdoor air cannot be scented: there is no ceiling, so the volume above the terrace is effectively unbounded, and even a light breeze replaces the air over it continuously. A machine rated for approximately 1000 cubic metres of enclosed air is rated for a bounded room, and putting one on a terrace produces a faint smell within a metre of the unit and nothing at all beyond it. What works outdoors is proximity, and that means flowers. Fresh mogra, rajnigandha or rose strung along the route people walk to the terrace, potted jasmine near the seating, petals in a shallow water bowl, all placed close enough that people pass within a foot or two of them. Then spend your fragrance where it does work: the front door, the hall, the stairs, the room where bags are left, the washrooms, and the indoor space people come back into. That indoor return is a genuine moment, because a guest coming in from open air has a fresh nose again.
Which SOSA registers come with the machine, and can I choose?
The SOSA Vaayu at Rs 11,999 ships with four hotel-inspired waterless blends in the box, chosen as one of three bundles at checkout, which is unusual enough to be worth stating plainly because most people assume fragrance is sold separately. Bundle A is Ritz-Carlton Inspired, Westin Inspired, St. Regis Inspired and 1 Hotels Inspired. Bundle B is Westin Inspired, Shangri-La Inspired, Four Seasons Inspired and Ritz-Carlton Inspired. Bundle C is St. Regis Inspired, W Hotels Inspired, 1 Hotels Inspired and Four Seasons Inspired. For a house that is going to host an engagement and then the rest of a wedding week, Bundle A is the most versatile because it gives you two quiet white teas for daytime functions, a dry green for a grounded house and the plush amber for the evening. One format note that matters: the Vaayu runs waterless nebulising oil, while the separate SOSA Hotel Collection at Rs 299 for 15ml is water-based and goes into the ultrasonic machines only, meaning Boond at Rs 899, Sukoon at Rs 1,899 and Megh at Rs 3,499. The two are not interchangeable. For ongoing fragrance supply, message us on WhatsApp.

About this guide: Written by Sonal Sahani, ISIPCA Versailles-trained founder and perfumer at SOSA Home & Body. Product recommendations reflect the SOSA home range; the sizing logic applies to any brand's systems.Facts verified August 2026: The SOSA Vaayu (₹11,999) is a waterless cold-air nebulising machine covering approximately 1000m³, with Bluetooth app and timer scheduling. It ships with four hotel-inspired waterless blends included in the box, chosen as one of three bundles at purchase: Bundle A - Ritz-Carlton Inspired, Westin Inspired, St. Regis Inspired, 1 Hotels Inspired; Bundle B - Westin Inspired, Shangri-La Inspired, Four Seasons Inspired, Ritz-Carlton Inspired; Bundle C - St. Regis Inspired, W Hotels Inspired, 1 Hotels Inspired, Four Seasons Inspired. Format distinction: the Vaayu and the HVAC systems run waterless nebulising oil, while the separate SOSA Hotel Collection fragrance (15ml ₹299) is water-based and runs in the ultrasonic machines only - Boond (₹899), Sukoon (₹1,899) and Megh (₹3,499). The two fragrance formats are not interchangeable, and the Hotel Collection bottle does not go into a Vaayu. SOSA Aangan (₹25,999) and SOSA Meenar (₹38,500) are HVAC nebulising systems for approximately 8,000-10,000 sq ft and 12,000-18,000 sq ft respectively, ducted into central air-conditioning. Reed diffusers need no power and make no noise: Morning Freshness ₹749, Garden Bloom ₹799, Evening Calm ₹799, Mountain Breeze ₹849, Fresh Brew ₹849; 130ml from ₹1,249; duo sets ₹1,498, ₹1,548 and ₹1,598. Scent perception is personal and varies between people in the same room, and coverage figures assume connected air volume rather than a partitioned floor plan. Ventilation, cleaning and air-conditioning come first; fragrance is an addition to a well-kept home and never a substitute for any of them. SOSA blends are SOSA's own hotel-inspired interpretations; SOSA is an independent Indian fragrance house and is not affiliated with, endorsed by or connected to any hotel brand. Made in India, cruelty-free and vegan. A portion of every order supports girl-child education through Nanhi Kali. Ongoing fragrance supply is arranged with SOSA on WhatsApp: +91 96192 18531.
