Some girls can pull it off. Some can't. Some look too slutty. Some look too hard to get.
It depends on a few things.
Overall, though, I'm not a fan of MY girl doing it. Females may not ever admit to this, but when they wear "showy" clothes, they are wearing them to "show" something off. And that's, NORMALLY, directed towards the opposite sex. Whether they are a cheater or not... it's for a reason. But, I've had a few (every girl I've talked to it about) just absolutely ASSURE me that it's just because it's "COMFORTABLE" or some other lame excuse lol.
Post above pretty much says how I feel that they feel about it and reasons for doing it (wearing skimpy shirts/short shorts): "It's a major turn on to know I am being watched because of my teasing attire. Call me slutty or whatever, it doesn't matter." It's always about the opposite sex. Not to be a hypocrite, it's our human nature, if we are straight, to try and attract the opposite sex. I'm a male, and hell, one of the first thoughts that goes through my head before wearing something boils down to "will chicks think this is stupid/makes me uglier". It's not on my mind if I'm not going out into public, but when I do, chicks are on my mind. And I'm on their mind, that's why they get all skimpy ;-)
