It's all a matter of persona and setting. Personally I'm one of those people who falls over giggling at the fetish look for Dommes, so I don't really mind the lack of official Dom wear (YKINMKBYKIO, I know, I know...), but anything borrowing from male positions that are considered naturally dominant or dangerous works. If I were a man I'd go for the overly polished buttons + fop look, like a proper deadly, but not in the least bit brutish, cavalry officer.

But save me from the black leather vests.
