The one time I tried it (granted it was a half-tech half-marketing event, more like a meetup than anything technical), people treated me really weird and called me miss. UGHHH :(

I don't wear jeans except at tech conferences and the like but I really appreciate the almost anonymity they offer! (EXCEPT THEN I FEEL WEIRD LIKE I'M NOT MYSELF BUT... but maybe I'd really rather that people not see me in those contexts so it balances out in a really weird manner)
