I purchased this item, which was worn once, and have used it a few times in the pool (with swim diapers). I am selling it because my child has outgrown it. I think it can still be used. The size is about 80, which should be just right. My child used it from 10 months to 1.5 years old. I don't see any pilling or stains, but please refrain from purchasing if you are sensitive to these things, as this is a used item and has been used by a child. - Brand: hakka baby - Size: SS - Design: Shark pattern - Color: Blue/Yellow/White Thank you for looking.
