Rai Nani Polyester Button Down Aloha Shirt With Pocket

EUC hard to find polyester Aloha shirt which was popular in the 70’s and 80’s. Shoulder to shoulder measures 17.5”, armpit to armpit measures 22”, sleeve length measures 9”, length from collar to hem measures 29”. Not sure of the size, but I think it’s a medium. Design is an island against the mountains.
