And that right there is why I'm glad I'm in academia - practical, non-fussy dressing all the time.
As for getting harassed, I don't think I've been targeted as a woman. Of course, it helps that I'm relatively tall, a bit overweight (with really muscular biking legs), and usually just dress in plain shorts and a T shirt when I'm on the bike. Lots of people mistake me for a guy from behind.
