A store's scent shapes how long customers linger and how the brand is remembered on the way out, independent of what they buy. Fashion, beauty and lifestyle retailers use it to reinforce identity at the point where a customer is closest to the brand.
It applies just as much to a single flagship defining a new store concept as to a dealer network wanting every outlet, however small, to feel like the same brand. The strategy differs by scale, but the underlying question is the same: what should this brand smell like, consistently, everywhere it is present.
