This is a 100% wool knit sweater from Ralph Lauren. It has shrunk from washing and feels like a size 130cm. Please check the actual size in the photos. My son, who is a large first grader, used to wear it. He doesn't wear it much anymore, so I'm selling it while it's still in good condition. The tag has been cut off. There are wrinkles from storage. I don't think there are any noticeable stains, but please consider it as a used item.
