Vintage 70s Gingham Jacket

Vintage 1970s large gingham print synthetic textile jacket. This jacket appears to have been homemade and well loved. It is missing two buttons and has some slight staining on the front, and could use a little TLC, though it is still wearable in its current state. I'd call it a modern-size medium. Measurements (Rough): Armpit to Armpit (buttoned): 20" Length (HPS to hem): 27"
