This is a simple, so-called ordinary white long-sleeved school shirt. I only bought it recently for high school entrance exams, so I've only worn it a few times. I think it's a design that can be worn in either junior high or high school. I bought it from a select shop that handles school uniforms, so it's well-made. The size is 170cm (my plump daughter who is 158cm tall wore it). Approximate flat measurements are: Shoulder width: 42cm Body width: 52cm Sleeve length: 55cm Length: 70cm (I'm entering it as a size L because this size isn't listed.) Thank you for looking.
