It's difficult to tell because of the way you're standing, and also I think the dress you're wearing has a slight bubble hem, which makes your hips seem bigger than I think they are, but I'm not sure. Do you have a picture of yourself standing straight, looking forward with your arms down? Right now if I had to guess, I'd say either you're a Pretty Pear or maybe a Racy Rectangle, but again, it's difficult to tell.
