Here is an awesome vintage sweater from the 1970s. It feels like acrylic or a blend. Great striping of blues, white, and red. Fairly light weight, soft and comfy. It's in amazing condition, and has years of life left. Here are the measurements taken laying flat. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 16"

Shoulder to end of sleeve (including cuff) 21"

Length 20"

This item is sold from a vintage boutique in Roanoke, VA.
