L.L.Bean denim long-sleeved shirt with a check-patterned lining and two pockets. - Color: Brown - Design: Check-patterned lining - Pockets: Two front pockets - Style: Long-sleeved shirt - Material: Cotton or denim-like material This is a foreign M size, so I think it's equivalent to a Japanese L size or larger. It's a very sturdy shirt, 100% cotton, typical of L.L.Bean. It can also be worn as a jacket. Please note that the check-patterned lining has some pilling. I hope someone will wear it again ^_^ I'm sorry, but I can't offer a discount m(_ _)m
