VINTAGE 100% Wool Ski Sweater - Mock Turtleneck - Size S/M

100% wool, mock turtleneck sweater in excellent condition. Bright purple with yellow and red block stripes on the sleeves. Size tagged as a medium, but it fits snug - I would say more like a small or extra small, depending on how you prefer it to fit! Ribbed knitting gives it some stretch. Measurements in photos.
