This is a shirt I received as a souvenir from Bali. It's a men's L size. It doesn't show through because it has a sturdy lining. It can also be worn as a light jacket over a T-shirt. It's made of a material that doesn't wrinkle easily, so I think it's easy to take on trips. The material isn't specified, so the details are unknown, but it's not cotton. Width: 53cm
