Vintage 1970s KMART Waffle Weave Mesh Shirt Black Size L

Vintage 1970s KMART Waffle Weave Mesh-like Shirt Black Size L. Great vintage condition! Cool & unique piece. 100% Polyester! Loud & clear on the tag. They were excited about polyester in the 70s! Seems like kind of a precursor to the 1980s style mesh type shirts. Slightly sheer, see photo with my hand under the fabric. Made in Japan. Please review measurements because sizing has fluctuated over time and this is 40+ years old. Flat measurements approximately 17" pit to pit. 21" shoulder to bottom edge.
