Miki House Girl's One-Piece Swimsuit Navy and Checkered Swimsuit with Frills Size 135-145 - Design: One-piece swimsuit with frills - Material: Polyester blend - Straps: Thin straps Thank you for viewing. I used this for pool use from kindergarten to lower elementary school, but it has been stored at home for several years because my child outgrew it. The elastic hasn't deteriorated much, and although there is some pilling, I think it can still be used. The size is as stated above, but it runs small for a swimsuit. Please refer to the photos with the measuring tape. Please refrain from purchasing if you are concerned as it is a used item. Also, for hygiene reasons, we cannot accept returns.
