This is an Aloha shirt from Bunkaya Zakkaten. I bought it at the Shibuya store around 1981-82. The material is rayon et (100% rayon). It has shrunk considerably due to being rayon. Length: approximately 60-68cm, Width: approximately 50cm, Shoulder width: approximately 42cm. There is fraying around the collar and on both chest pockets. There is also yellowing around the neckline. Please understand that this is a vintage item.
