Since you didn't really get a girls perspective on why one would like dresses or skirts, I'll answer, because I don't like wearing them.
1. I like to be an active person, run around, jump, wrestle with my bf. I can't do those things without being fulling aware of where my dress or skirt is to make sure I don't end up being inappropriate in public. It's a distraction.
2. If its a formal event, I have to wear pantyhose. I hate pantyhose. It's so confining, and it gets all twisted around my waist for who knows what reason. I at least found a solution for that, garters and thigh highs, but that only works with certain dresses and skirts.
3. It's extra work in the bathroom. Not by much, but you have to remember to check to make sure your dress or skirt isn't accidentally tucked in your underwear. With pants you don't have to worry about that at all. But with dresses and skirts, there's a lot more wardrobe malfunctions you have to be aware of.
4. It's drafty. If you're not used to wearing skirts and dresses on a daily basis, it's an extremely odd feeling have a breeze all the way up there. It's much chillier wearing a skirt or dress than pants or shorts. Which is probably why many girls love sun dresses, but you still have to get used to the draft.
I can't think of another reason besides more scenarios for wardrobe malfunctions, but I think it's a pretty basic list that most non-feminist girls who dislike dresses and skirts can relate too.
