This is a black shirt made of 100% cotton, a cool and breathable material. It has a length of 67cm, a width of 50cm, and a shoulder width of 43cm. The size is labeled as S, but it's an American size, so it's actually a size M. The cool material makes it wearable from spring through early autumn. It's easy to match with anything, such as denim, chinos, or shorts, and it's a button-down, so it can also be used in slightly more formal settings.
