All items are from Uniqlo. All undershirts are the same size. I've cut off the tags, but I think they are size 80. (White, light yellow, white with pink polka dots) Rompers are short-sleeved and sleeveless. The short-sleeved ones are probably size 80, and the sleeveless ones are probably size 90. The sleeveless ones have been used about 1-2 times, but the others may have some signs of wear. There appear to be no noticeable stains or damage. Please check the photos and purchase without any complaints. If you are concerned about minor details, please refrain from purchasing.
