Places to find clothes for 13 year old girls?

I'm pretty limited on options when it comes to clothing, because I'm kinda small. I can wear 12-16 in girls sizes. Almost always I'm a 14 but it depends on the brand. Then in juniors, I can usually wear XS and 00-1ish. but again, it all depends. Most kid clothing is too young for my taste and the juniors doesn't usually fit. Where are there places that have good clothing that isn't too expensive that comes in my size? I love Aeropastle and i know hollister and abercrombie are good for my size but they're usually way overpriced. Also i can maybe find a few things at jcpenney, kohls, and sears.
