I'm telling ya though. . . I really don't think that I can pull off #4. That's for stick figures, not for curvy ones.

I just thought it was pretty, so I put it on there, but the more I think about, only #'s 1 and 2 were DESIGNED to hide hips. Here, these are my only other options: (I think you'll agree that 1 and 2 were the best, and if not, please post which one of THESE you like the best for a 17 year old girl!)

EDIT: This one is KIND OF pretty too, but maybe too old (?):
