Speedo competitive swimwear! Size is M, and it was worn a few times by a child who usually wears size 150-160. These swimsuits are made with thicker fabric, are chlorine resistant, and have a design that makes the bust less noticeable. I bought it new, but I'm selling it because my child, being at that age, doesn't want to wear a legless style. It's in beautiful condition, having been worn only a few times! How about it for daily practice?
