Homemade Vintage Crochet Vest

Genuine vintage item given to me by the creator who wore it in the 70s. I've never worn it and want to pass it on to a good home. there is slight unraveling at the upper back edge but could easily be repaired by someone who knows basic crochet. Measurements (rough): armpit to armpit: 17" (unstretched) length (HPS arm strap to hem): 20"
