This is a Back Number check shirt. I bought it for my son at a used clothing store, but he never wore it and outgrew it, so I'm selling it. I washed and ironed it once after purchase and then stored it at home. It has snap buttons except for the top button. Width: Approximately 53cm Length: Approximately 77cm (back side) - measured flat, amateur measurement Material: 100% cotton flannel Please purchase if you understand that this is used clothing and has been stored at home.
