These are outgrown items from my child. They didn't like the ivory color and barely wore them before outgrowing them. They are AIRism pants, so they are thin and smooth. The waist is adjustable. During inspection, I found one stain on the rear, but I don't think it's very noticeable. Please check the photos, and refrain from purchasing if you are concerned. For those who understand that these are used children's clothes (^^) - Brand: UNIQLO - Size: 140 - Material: 63% Polyester, 37% Rayon Thank you for looking.
