Vintage Joseph Ribkoff striped off shoulder top

Black and white striped off the shoulder top by Joseph Ribkoff in excellent vintage condition. The part that goes across the shoulders can also be worn as a cowl neck. Listed as US size 6, shown on a size small with 31” bust. It’s very stretchy and I believe meant to have a tight fit, so it would better suit someone with a larger bust than me. See measurements: Pit to pit: 16” Length: 19.5” Material: not listed, but feels like a super soft good quality cotton jersey and spandex mix
