This is an open-collar shirt from Stussy. It's navy with white piping, and the design resembles a pajama shirt, which is quite rare. The material is 100% polyester mesh, and when held up to the light, it reveals a striped pattern. I think it will be cool and comfortable to wear even in the summer. The details are well-considered, such as the Stussy lettering on the buttons. I am 180cm tall and it fits me perfectly.
