This is a Bart Simpson t-shirt. The long-sleeved one is size S, but since it's a foreign size S, it's equivalent to a Japanese size M. As shown in the third photo, there's a stain on the shoulder. Also, since it's white, the collar is slightly dirty, but it's barely noticeable. The short-sleeved one is a women's size M, but it can be worn by men who are small-framed. It has a longer length.
