well, the thing is, girls--except for BFS, apparently, you go girl!-- choose to wear those stupid clothes, so I have no sympathy whatsoever in that regard (except when you're forced to wear a dress for a wedding or something). and girls DO get a LOT out of wearing that uncomfortable crap...a girl dressed "hot" generally does look better than a girl not dressed "hot", so they attract more attention and get all the benefits associated with beauty. so in order to compete other girls dress "hot". until the only people who dress like rational human beings are the girls who say FUCKIT.
i go with bigfakesmile on this one. dress normal. if you do, you will look a little less hot, but your own comfort is worth it. (and it probably means you are cooler, too).
