Pants versus Skirts

As more women are likely to wear pants than men to wear skirts, I’ll use women as the core of my thesis [I don’t care either way myself anyway]. For a reason I can’t really comprehend [yet or maybe never], some women look great in skirts and others in pants [so I’m convinced the other way around must also be applicable]. The question remains: why is that? Would life be any different if we’d run around the way we were born?
