This is a Ralph Lauren rugby shirt. The size is 10, which is equivalent to a Japanese size 150cm. There is no noticeable staining on the white collar at first glance, but some people may be concerned depending on the lighting or how they look at it. Please understand that this is a used item. The "P" on the chest is made of felt and has some slight wear. I think there is little wear on the body of the shirt. Individual perceptions vary, so please purchase if you are not concerned about minor details. Please note that there may be wrinkles from storage and that it will be sent in simple packaging.
