I bought this in the US, so the size is listed as S, but I think it's about the same as a Japanese M size. Please refer to the photos for the width and length. It's a blue-系 check pattern, and it looks great worn on its own, layered with a white or gray inner shirt with the buttons undone, or tied around the waist as an accent. There's a pocket on the left chest, although it's hard to see in the photos. The collar is button-down. I will fold it up small for shipping. Please understand that this is a used item and may have fold lines.
