A Winter Formal?

Middle school dances are so much fun!! You can get away with wearing whatever you want. I think you shouldn't worry about your legs, don't wear something too long, but if you're really insecure, wear a dress that goes just past your knees. I'm chubby but I might wear a mini to the next dance. I wish I had been more secure with my appearance when I was your age--everybody's going to be worrying about what THEY look like, not you. I think you should wear blue or pink, since you're blonde, and maybe just straighten your hair and leave it down.

Here's the kinds of dresses I'm thinking [I wish I could pull these off!!]::
