Because we're not wearing men's clothes. We're wearing women's clothes. Personally, I wear a size 8 tall. I don't think that men's clothes are sized like that.
Maybe you're comparing current women's styles to the styles that women wore in the 1950s?
Edit - Men can redefine their style too, if they want to. In fact, I saw a skirt designed for men on Zappos a few weeks ago for $75 but it is no longer available. It was skirt designed for mountaineering. There are more man-skirts featured here, just click on the arrow for all seven slides:

These men don't look gay to me at all.
