Lol, this thead's funnier than I expected.

But yeah, I'd blame society. You know, social norms and the pressure to conform and all that. Plus, I'd say that guys are quite a bit more easily stimulated visually than women are, sexually speaking. Guys get aroused by looks very easily, women do to, but not to the same extent or as often, usually. Therefore, women have way more pressure to look good so that they can impress and get the attention of the man. I mean, you don't see many men parading around in "revealing" clothing to get the attention of women. Guys try to show off their physical abilities to impress women. A lot of guys rarely put much thought into how they look or what they wear. That's my opinion anyway...
