Vintage Short Sleeve Button Down Shirt from Sea Isle by Arrow

Here is a cool vintage short sleeve button down shirt from the 70s by Arrow, under the Sea Isle label. 65% polyester, 35% cotton. Striped fabric in beachy pastel colors. Six button front with a pocket on the left breast. It's super light weight, crazy thin, sheer, soft and comfy. It's in amazing condition with tons of life left! The tag says Large but here are the measurements taken laying flat. (refer to the last pic above to see how I measure shirts)
