This is a 1950s rayon shirt. It was reproduced by Sun Surf in 2009, and the original is quite valuable. Although there is no material label, it is likely silk or silk x rayon. It's smooth and cool, so it should be useful even in this still-hot season. There is some wear, but no noticeable stains or damage, and the condition is good for a vintage Aloha shirt of this era. There is a small damage repair on the collar (sewing and reinforcement with thin adhesive fabric on the inside), minor scratches, and stitch reinforcement. The size is L, and it fits loosely on a person who is 172cm tall and weighs 63kg. Length: 68cm Shoulder width: 48cm Width: 60cm Sleeve length: 20cm
