Purple and white stripe sweater - tennis sweater - v-neck sweater

A 1980s (my educated guess) sweater in nice clean white and purple stripes. The tags are missing, but it feels like acrylic. Excellent secondhand condition. Women’s Size: Medium Shoulders: 15.5 inches Pit-to-pit: 20 in Sleeve (from shoulder seam to cuff edge): 23 in Length: 25 in
