This is a collaboration short-sleeved shirt between Minedenim and Wacko Maria. The size is S, and the color is black gray, exclusive to Minedenim directly managed stores. Although it's labeled as S, it has a large fit. The measurements are approximately 73cm in length (from the back of the collar) x 62cm in width (from under the armpits) x 48cm in shoulder width, so it can be worn without any problem by those who usually wear M to L sizes.
