Vintage Long Sleeve Sweater by Jantzen

Here is a super cool vintage "hand knitted" sweater from the 70s/80s by Jantzen. 78% silk, 20% acrylic, 2% wool. Sweet, subtle geometric design in off white, brown, and pink. Shoulder pads are present. It's medium weight, soft, warm, and comfy. It's in excellent condition with tons of life left. The tag says Large, but here are the measurements taken laying flat. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 20"
Sleeve 22"
Length 23"
