IMO I don't think woman/girls period should dress like a whore. I've heard from many many friends that are guys and they would rather be seen with a woman who doesn't show her ass, boobs, or whatever else to everyone that walks by. It makes you look to easy, trashy and whorish!
Woman should respect their bodies, and respect their men! I'm not saying wear turtlenecks and long pants 24/7 but don't show are your goodies!
