I've cut the size tags off of many of the items. In the 6th photo, the Adidas blue T-shirt is size 130, the Adidas running navy shirt is size 160, and the others are size 140. I don't think there are any stains, but they are generally faded. The polyester fabrics have snags and pilling (around the neck and on the sleeves of the long sleeves). (See photos) The pants have hardly been worn. They have adjustable waists.
