This is a Theory check shirt. I think it's very useful and can be worn often. I'm selling it because I don't wear it much anymore. The large check pattern is quite rare, and I think it stands out among check shirts. It's convenient for casual office wear or going out. The size is XS, but it fits me perfectly, and I'm 175cm tall. So, I think it's about the size of a Japanese M. Shirt Type: BD shirt (button-down) Color: Green Sleeve Length: Long sleeve Pattern/Design: Check Material: Cotton
