Well I have seen a lot of girls dressing like this when I was in uni. Never middle school though.
I guess you need to be around more adult minded people before you could put something like that on.
I wouldn't have mind myself if you were at my middle school but I do know a whole lot of people who just like making fun of people slightly different than they are.
Just that you know there is nothing wrong with dressing the way you do.
The other people just say shit like that because they mostly don't want to feel insecure about themselves.
I think it makes them feel bigger and better than the rest of the school.
I would still recommend waiting until you're around more adult minded people.
Otherwise there is a chance you're going to feel bad every day at school.
