This is a button-down shirt from MUJI. It seems they don't sell it anymore. I wore it as a fashionable item. It's also convenient as an outer layer. In winter, layering with a turtleneck as an inner layer makes it even more stylish. When it's hot, you can just take the shirt off. Please understand that this is a used item. Ivory button-down shirt, size 100, with a chest pocket. - Size: 100 - Color: Ivory - Design: Button-down shirt - Pocket: Chest pocket Thank you for looking.
