This is a Papas swimsuit. It's size M and comes with a case. I bought it new at Papas in Isetan, Tokyo, about 20-30 years ago and wore it once. *I wore a supporter underneath. I haven't used it since and have kept it at home. It's been stored in a smoke-free, pet-free home with mothballs. I don't see any noticeable stains, but there's a crack in the "P" print. *See the 4th photo. I am an amateur, so please understand. Please judge the condition based on the photos.
