Only rinsed with water, brand new and unused. I bought this for a trip and washed it, but I received another swimsuit before the trip and wore that one instead, so this one is brand new and unused. It covers up to the belly button and has sleeves, so you don't need a rash guard. It's a separate type, so changing diapers should be easy. It's 6-12 months, so it should fit a child who wears size 70-80. A cute Minnie Mouse design purple swimsuit set, a combination of a long-sleeved top and shorts. - Color: Purple - Design: Minnie Mouse print - Style: Long-sleeved top and shorts set - Features: Polka dots Please understand that this item has been stored at home, and we appreciate your purchase.
