"Honest", "authentic" and "myself" -- those all mean the same thing, I think. Nice one! Another popular descriptor. I don't feel like I need it on my list, though, because I do dress like myself -- I can't really dress any other way. (Although I did try it once -- dressing like someone else, I mean -- at the beginning of my teaching career, just so I wouldn't look like a student. I tried to dress older, and more business-like. It felt awkward).
Mona -- absolutely, I think you could describe a person's style as "confident". I wouldn't mind having that one as a descriptor, either.
kkards -- you could hyphenate it. "Put-together"? I bet you could get away with that.
Amy -- I like distinctive, too. Gee, there are a lot of words that I want to appropriate.
