This is an old Aloha shirt. The subdued base color with the flashy, fluorescent-like floral pattern is lovely. There's no material label, but it's not rayon; it's cotton or a cotton blend. It's relatively thick and has a crepe-like wrinkled texture. Shoulder width: 39cm Body width: 50cm Length: 65cm Sleeve length: 21cm I think it's equivalent to a size S-M. Please compare it with a shirt you own before considering a purchase. Please refrain from price negotiations. No comments, immediate purchase welcome!
