Hi Faith-

DD should be in a small (7/8) based on the size chart on the AG site, but she does wear a medium (10/12) in some other brands. We're going to AGPC tomorrow and we're planning on getting her the girl-sized outfit and PJs so I'll let you know how they run on her. Is there an outfit in particular you're interested in? I could have her try it on for you to see how it runs.

Just let me know!

Cheri
