Halloween Costumes for a 13-14 year old? NOT Sleezy!?

I want my halloween costume to be pretty and more "my age" than the years past. I do NOT want it to be slutty but I dont want to look like a baby, either. I sure hope that makes sense. If this helps with ideas, I love music (especially Taylor Swift, Kesha, and Lady Gaga). Oh BTW I want it to be pretty AND scary at the same time. I hope Ive sparked some Ideas cuz Ive got nuthin. Thanks for answering!

Choose something cute like a cheerleader or miss america,
and get some costume makeup to make cuts and fake blood!!
This will make people look twice at your costume!!
