Thank you for viewing. This is a set of matching long-sleeved check shirts from Coen for parents and children. The adult size is a women's M. The child's size is 130cm. The material is 55% cotton and 45% linen. Since it contains linen, it's cool even in early summer and can be worn as sun protection. We bought these as a matching set for parent and child, but we've only worn them once or twice. I don't see any noticeable stains or anything, but these are used items, so please understand. If you have any questions, please comment.
