Ralph Lauren Long Sleeve Polo Shirt Black Size: Junior XL, suitable for 16-year-olds I believe it's similar to an adult's S size, but please check the photos for details. This is a shorter length type. Made of 98% cotton and 2% spandex, it's stretchy and comfortable to wear. Features a lovely design with a gold logo. There are no noticeable stains, and I think it's in relatively good condition. Will be folded small for shipping.
