These are UNIQLO leggings. The size is 80. Perfect for daycare or everyday wear. I used them for one season (autumn/winter) last year, but my child quickly outgrew them. There may be some minor pilling, but I personally don't think it's very noticeable and they are still in good condition. Please refrain from purchasing if you are concerned, as these are used items that a child has worn. *I have a cat. The cat is not allowed in the room where the items are stored, but there is a possibility that cat hair may not be 100% removed. Please refrain from purchasing if you have allergies or are sensitive to this. UNIQLO Leggings Pants Baby Kids Daycare Kindergarten Dinosaur
