hips are big

Better? Better than what? You're question is not clear.

I can't say that nothing would make them smaller because there might be something, but women's hips tend to be wider because we have to bear children. Since your name is crazy girl, I am assuming that you are a girl--LOL. Chances are your hips probably won't get much smailler.

I'm not an expert or anything, but these are my thoughts!!

I hope I've helped!!
