This is a baby swimsuit with built-in diaper functionality. I'm selling it because my child is now potty-trained, and it's only been worn a few times. There's a small stain on the back, but it's not very noticeable. Please check the photos. Other than that, it's in very good condition. The size is indicated as 3T, but it runs a bit small, so it's probably around 90-100cm. It has been stored at home. Please understand that this is a used item before purchasing.
