Should the Same Footwear Signature Scent Be Used in Mumbai, Delhi, Bengaluru and Hyderabad?

Yes, and that is the only version of this that works. Take the register first. A signature fragrance is a brand asset in the same way a shopfront, a bag or a font is, and its whole value comes from being repeated. A customer who knows your Mumbai store and walks into your Hyderabad one should recognise something without being able to name it. Changing the fragrance by city destroys that for no gain at all, and the reasons owners give for wanting to - it is more humid there, the store is smaller, the manager prefers something fresher - are all reasons to change a setting rather than a scent. Choose the register from the stock and the interior, as you would for a single store: dry pine, sage and cedar under leather and dark wood; lemon, peppermint and eucalyptus on a bright sneaker floor; rose and jasmine in an occasion boutique. Then hold it across the group for years. Now take the four rooms, because they are genuinely different. Mumbai is humid for a long stretch of the year, which slows evaporation, makes a passive product read quieter, and rules out a water-based ultrasonic unit through the wet months near cardboard, carpet and leather. Delhi behaves like three separate rooms across one year - a hard-chilled dry May, a wet August, a still January with the door propped - so it needs a level that moves twice a year rather than one that is set and forgotten. Bengaluru is the mildest of the four and often the least mechanically conditioned; a store with openable windows and modest cooling has calmer air, which means placement carries more weight and a lower setting usually reads correctly. Hyderabad runs hot and dry for long stretches, so plant tends to work hard, air moves, passive products deplete faster and dust needs naming on the cleaning rota. Then take the buildings, which vary at least as much as the weather. A sealed mall unit, a street-facing shop whose door stands open and an older building with real windows are three different problems, and your four stores may well be three of them. Floor area varies too, which is why one brand can honestly run reeds in a 400 sq ft unit and a waterless machine in a 1,800 sq ft one without any inconsistency at all - the register is identical and only the delivery differs. What holds this together is a rule rather than a number. Standardise the fragrance, the placement principle and the test - noticed on arrival, settled within a minute, judged at six on a Saturday with the floor full, and overruled by staff who say it is too much. Never standardise an intensity step or a reed count across buildings that do not breathe alike. And keep the frame honest: this is a brand and interior decision, and we make no claim that it affects sales, footfall, browsing time or what anybody buys. Ask for a store scenting plan with your four floor areas and building types.
