Why wear something like that if you don't want the attention?
Yes, I bet some girls will say "oh they make me feel attractive" and say "I feel better in them" or "oh I happen to like the look of them (slightly coincidental most of the clothes you like are revealing like that isn't it??) Obviously something else going on.
I'd say a woman who wears revealing clothes and finds that it gives her more confidence than dressing modestly is obviously a woman who bases her self-esteem on the pulses of male reception. This is their genes at work here, as everyone surely wants to be "attractive" and and obviously like the attention as it gives them more options for potential mates to notice them, thus able to pass on their genes. However they don't like (or often don't believe this) as they have constantly told themselves when trying to rationalise this behaviour that it is because they "feel nice" or "feel comfortable" or "feel better" and as everyone knows, if you tell yourself something enough times you begin to believe it as truth, even if it is a lie.
I also think they don't understand there is a VERY fine line between being trashy and sexy - and since hollywood pushes it to the breaking point - they will probably never understand. It has partly to do with today's celebrities, television and young people's role models. It's socially acceptable now to have boobs popping out of dressing and your "peek-achoo" exposed as you exit from a car (Thank you Tara Reid, Paris, Britney and Lindsey)
Who else agrees?
