Here is a super hip looking long sleeve sweater from the 70s by Collageman. 100% acrylic. Deep reddish orange sweater with white accents. Three faux leather buttons at the collar, and a buttoned pocket on the left breast. Lighter weight, but warm, soft, and comfy. It's in amazing condition with lots of life left! The tag says Medium, 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"

Shoulder to end of sleeve (including cuff) 24"

Length 24"

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