Description - Bright yellow men's beach shirt from the 60s with large white buttons. it has 4 large pockets that button closed. (The bottom ones are big enough to fit my IPhone) There was most likely a swim trunk in this same fabric or a coordinating print available for sale as well so the customer could wear it as a cabana beach set.
