This is a shirt from Green Label. The size is XS, but it's a bit large even for me, and I usually wear a size S, so I'm listing it as a size M. Actual measurements are shoulder width 42cm, body width 48cm, and length 73cm. Please allow for some error. The color is white. Here's a description of the brand: The "1_OF MINE" series from green label relaxing. These are items that become the starting point of your styling, the ones you reach for in your closet.
