This is a long-sleeved shirt in size M, made of 100% cotton with a purple check pattern. Measurements taken by a non-professional, laid flat: shoulder width 38cm, sleeve length 58cm, length 61cm. Because it's a check pattern, it's difficult to see, but there is some discoloration around the collar and shoulders (see images 2, 4, 5, and 6). Please understand this before purchasing.
