Here is a rad long sleeve sweater by Ifi. 100% acrylic and made in the USA. Nice purple fabric with black accents throughout. Fairly light weight, soft, comfy, and in amazing shape! The tag says large, but here are the measurements. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 23"
Shoulder to end of sleeve (including cuff) 21"
Length 25"

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