I want to make
this for my 12 (soon to be 13) year old daughter. I'm not sure what size to make for her. How can I figure it out? She's 5 feet tall and about 102 lbs. I would think a small or medium, but the only problem is that she is a bit large in the chest area (32D). I'm worried that if I make it too small it will fit right around her stomach but be stretched too much across the chest. On the other hand if I make it too large, it'll be baggy across the stomach area (and a corset top isn't supposed to be like that

). Help!
