I am not up on the research, but I would be surprised if there were no connection.
Here's a few guesses that I'd venture, just based on my experience of people in general.
I'd say that if you are a lover of many fragrances, it could be a connection to a many faceted personality. (I'd argue that all people have this possibility, but many people live in fear of some of the facets of their own selves and so remain rather flat personalities)
I'd also guess that the bolder the personality, the bolder the fragrance choice. For myself, I'm a pretty bold woman and I'm not afraid to wear a scent that others don't like, or feel is strong. Not that I want to offend or take no consideration, but I'm not wearing it for others and so while I don't want to wear so much that you can smell me a mile away, I'm not going to shy away from a scent just because someone might not care for it, if that makes sense.
This may be similar to bold, but I also suspect that the greater the variety of scents one wears, the more likely that person is to take risks.
I'll be interested to see what others have to say on the subject. Great topic Redrose!
