Vintage 100% cotton turtleneck knit sweater from the 80s

This sweater has unique ribbing on the arms and neck. It’s a fairly thick knit cotton and is in very good vintage condition. The sleeves are slightly batwing and are a bit shorter than modern sweaters falling about an inch above the wrist on me. It’s also fairly generous across the chest area so would fit modern medium to large as well. 😊 Measurements: underarm to underarm: 19.5” Length from shoulder to bottom: 20.5” Sleeve length: 17”
