This is a Nautica cotton knit. It's a size M, but since it's American sizing, it's probably closer to a size L. The actual measurements are approximately 67cm in length and 50cm in body width, so please use these as a reference. It doesn't seem to have been worn much, so I don't think there's any noticeable damage, but please understand that this is a used item that has been stored at home before making a purchase.
