Thank you for viewing. This is a long-sleeved checkered shirt from Zara. Men's US size S, equivalent to Japanese size M. It fit perfectly for someone 175cm tall and weighing 70kg. The fabric is a relatively sturdy, high-quality seersucker-like material with a crisp feel, so I think it can be used in a wide range of situations, from casual to formal! I wore it about 2 or 3 times and then stored it in the closet. As a bonus, I'll also include a striped shirt from UNIQLO. Please comment if you don't need it.
