The case for wearing one scent
A wardrobe is a modern idea. For most of perfumery's history, people smelled like themselves.
The signature scent is out of fashion. Every guide now recommends a rotation: something fresh for the office, something heavy for the evening, something forgettable for the gym.
Recognition compounds
A fragrance worn consistently becomes attached to you in other people's memory. That association takes months to form and cannot be bought.
Rotation is a retail strategy
It is not an accident that the wardrobe model asks you to own six bottles instead of one. Be clear-eyed about whose interest it serves.
The compromise
Two bottles. One that is unmistakably yours, and one for the weather the first cannot handle. Everything beyond that is collecting, which is a different and perfectly good hobby.
