Vintage Chevron Sweater Vest - Gray Black Zig Zag Stripes - M/L - 60s 70s

This vintage gray and black v-neck sweater has a zig zag striped chevron pattern. This 100% acrylic sweater vest doesn't have a size tag but I'd say it's a medium. Based on the tag and the dry cleaning tag I took off, I think it's from the 60s or 70s. Measurements: Armpit to armpit: 19.5" Length (top of shoulder to bottom of vest): 24.5" Brand: Teddi M, div. of Ted Martin. Condition: Excellent vintage condition. No flaws.
