Ralph Lauren Long sleeve polo shirt Black Size: Junior XL, suitable for 16-year-olds I think it's about the same as an adult's S, but please check the photos for details. It's a shorter length type. Made of 98% cotton and 2% spandex, so it's stretchy and comfortable to wear. It has a lovely design with a gold mark. There are no noticeable stains, and I think it's in relatively good condition. I will fold it up small for shipping.
