Swimsuit purchased from Nishimatsuya. It was worn for water play at nursery school, but there are no noticeable stains. There was a black spot on the part where the frill under the flower is lifted, but it is hidden by the frill when worn. There are also almost no pills on the bottom. I tried stretching it by hand, and I don't think there is any deterioration of the shoulder straps or fabric. However, I think it's from about 6 or 7 years ago, so I'm selling it at a low price.
