So I just recently ordered this and I was very cautious about sizing. I decided to order the child large instead of the adult small and I'm extremely happy I did!!! Just to let you know I'm 13 and quite petite yet tall/average height with very long legs, and a large fit perfectly!
This product was exactly what I needed! My daughter outgrew a competition costume before Nationals. I ordered this bra top, and it was perfect. It fit true to size, and it was comfortable. Comfort is important to my kiddo who has sensitive skin. There was no shifting of the top when she danced, and it was she like it so much that she wears it to class now that the season has ended.
