Thank you for viewing. This is a flannel shirt from Thomas Mason for J.Crew. The size is M. I believe this is a very rare collaboration shirt that is hard to find now. My body shape has changed, and the size no longer fits, so I will pass it on to someone who will use it. It has only been used a few times and is in very clean condition. Please understand that this is a used item before purchasing. Thank you. - Color: Multicolor - Brand: Thomas Mason for J.Crew - Size: M - Style: Slim Fit
