Edit: Question answered, thank you all!
Sorry if I posted this in the wrong section, I'm new.
Okay, I really want to dress up, but none of the outfits of the characters I like look like something I could wear. I'm very uncomfortable with my body, so the short skirts that nine tenths of anime girls wear are out. The problem is, I can't think of a single female anime character that I like (that I like and that can be recognized by their clothes, anyway) that doesn't wear a skirt. Because of this, I was thinking about dressing up as Alice from American Mcgee's Alice (she wears a long dress, so I'd be fine with it) but I'm worried that people would look down on me because that's not really anime. Would people be annoyed/look down on me if I went as Alice? Would they consider that as me not being dressed properly?
tl;dr : Can I dress as a non-anime character without looking stupid?
