Overall, this is a good product. The design is really cool, and my young daughter loves it. The only thing that I would have to mention about the singlet is that it seems a little tight. We went based on weight and my daughter was right in the middle of the YL weight range and the legs holes on the singlet I have to attempt to stretch out every time she wears it otherwise, she complains it is too tight. The body of the single though fits snug like you want but almost to snug if that makes sense. But overall, like I said good product.
After looking at several different sites and having worn BC in the past, she knew she wanted this singlet. Good quality stitching, but does run just slightly smaller than other BC singlets of the same size she has worn (not enough to recommend ordering up a size, though).
