Boys' swimwear. Size 100 It hasn't been used much, so it's relatively clean, but there's a slight snag on the rear. It's easy to put on because it only has elastic at the waist, no drawstring, and it was convenient not to have to worry about a drawstring. It has a lining. This is a used item. Thank you for your understanding. It will be shipped via Rakuraku Mercari Bin or Yu Yu Mercari Bin.
