Just wanted to add my opinion about the "asking for it comments", because I kinda feel like a leap of assumption has happened here.
To start, let me say I believe some women do dress up sexily with the intention of looking to pull, or have sex. It would be incredibly naive to sit here and say women are never looking for sex. We look for sex just as much as men do....otherwise, who on earth are all these straight men sleeping with? Women dress up gorgeous, which gives them confidence and makes them feel good about themselves (as some others have pointed out) and for some women, this is the ONLY reason they do it. But lets me realistic, most of us get dressed up, makeup on etc when we LEAVE the house. Not many of us get the mini skirt and make up and hair curled for a night in watching TV. Maybe this is because we do want other people to notice and appreciate the effort we went to, to look good. No, it doesn't always have to be about sex, but feeling desireable, or popular etc makes many people feel good. I personally support a womans right to dress herself up in mini skirt and what not and go get what she wants! Problem is, so many women are pressured under societal norms to feel incredible shame for A) wanting sex and B) going and getting it, so many women deny interest, deny wanting to feel sexy, or desireable, deny wanting a hot night with a stranger ....afraid of being labelled a slut.
Although I believe that women (just as much as men) seek sex, I don't understand the link between thinking that and therefore being in the same group as those who believe she was "asking for it" See, a woman choosing to go out on the pull is a woman making her own choices. She is a sexual agent, with the ability to do as she chooses and walk away from things she does not want. I support this and I support her choices. What I do not support (and actually find abhorrent) is another person taking away her choices, forcing his choices upon her.
What I am saying is that these two opinions (some women do dress for sex and She was asking for it) are seperate, unlinked opinions. One does not ultimately lead to the other. Heck, I could watch a person walk naked down the street with a sign around their neck saying "I'm looking for sex" and STILL believe this person is not asking for it.
Truth is, people do things for unique and individual reasons. So to answer your question, yes of course some women dress in a way they consider sexy because they want sex and or attention. However, they could also be doing it for fashion, to fit in and just because they feel confident and amazing when dressed up. I mean, lets be fair, if anyone (male or female) is going out in the hopes of having some sexual activity, they generally want to look their best at the time.
I think denying that women are sexual, sensual creatures occasionally looking for hot sweaty sex does us a mis-service. To state no women act this way, or that most "normal women act that way, is to keep putting pressure on women to conform to "the rules" or else fear being labelled. And now women can't win. You're frigid if you don't and you are a slut if you do. Everyone else is keeping score. It sucks.
Obviously, women (and men) in happy, healthy relationships are not dressing or behaving in certain ways with the intention of cheating. I do not believe anyone happy in their relationship are intentially dressing to go pull some random person for sex. Heck, there are even a great many people unhappy in their relationships that still would not do this, because they would feel crushing guilt and because somewhere, love exists between these two people. HOWEVER, I also believe that shacking up with a partner does not stop many of us flirting. In fact, flirting is such a a part of our makeup that apparently, we flirt without even knowing we do it half the time. I watched a show that said women actually walk different (more hip swaying) when ovulating. We are programmed to propegate the species and so we have strong natural urges and desires. A desire to feel wanted, a desire to feel sexy etc. The thing is though, we are intelligent creatures too and not many of us would leap into bed and cheat just because it was on offer. However, if we caught some attractive person flirting with us, or making eye contact and giving us a big grin...we don't get depressed....we feel uplifted. We are uplifted and uplift others by mild flirting, even knowing it is not going to lead anywhere or even though you feel happy...flirting boosts you a little when it happens.
It's so late and I think I stopped making sense about half a page ago lol, so I shall stop yammering on now. I just wanted to add my opinion.
