Can you give us more info?

In the UK, I would say that most 15yr girls probably have a dress size anything between 8-12. That's probably small or medium. I for one always have to go up dress size to accommodate books! My trousers are there a size smaller than my tops...

I'd say Small, but it all depends on how your body is shaped!
