This is an Oxford shirt called "Madison" from Kamakura Shirts. It's a simple 100% cotton button-down shirt, but it's carefully made with a collar that has no interlining and a particular manufacturing process. Made in Japan, the fabric thickness is also excellent. The size is 40 (neck) - 84 (sleeve length). It's about the size of a general size L. It has been dry cleaned, but please refrain from purchasing if you are sensitive to used items. It will be folded compactly for shipping.
