Baby boy swimwear This is not a set, but it comes with a rash guard. The swim pants were used for water play for one season, but they are still in good condition and can still be used. The pants are size 80, and the rash guard is size 90, but the rash guard runs small, so it should fit a child who wears size 80 perfectly. If you'd like, I have another pair of swim pants with a completely different color and pattern for a spare. If you comment, I will add photos and you can confirm, and I will include them for an additional 150 yen (these are also used for one season, but with less frequency).
