There's another way to do become associated with a particular scent - I'm thinking in terms of a family of scents with a common thread tying them all together. I'm thinking of what Mr. Guerlain does, for instance: stick with one house that has a particular house note or accord.
This way you get variety within that family of fragrances, and have the ability to choose something different to match your mood, match the occasion, etc. But for people who know you well, there will always be that consistent "something" that they'll recognize. You'll know it's the house note or accord, but those around you will just know at some level there's a consistency that's "you".
Any thoughts on this approach? What other houses besides Guerlain have a consistent and distinct house note or accord?
Even with this suggestion, I couldn't personally keep with this consistency and not stray I'd rather just use what I like.
