costume for teens

[pinkredNwhite]

My teen daughter is invited to a costume party on new year's eve. she asked me about the costume, and I said I'll make something for her.
I want to make something simple and appropriate, anyone have any good ideas what costume I should make?
it would also be great if anyone has any links to some good patterns
appreciate your help!
