pants somehow don't come off to me at as just male clothing. But dress somehow do come off to me as female clothing. I have never seen any skirts designed for men. I have however seen pants designed for women.
Only because that's what you're used to. But there was a time when slacks on women were completely unheard of. And I assume, had you been alive when women in pants started to become in vogue, you'd be arguing for the simplicity of when women couldn't wear pants.
