Here is a sweet long sleeve sweater by Diane Von Furstenberg. 100% acrylic. Vibrant red fabric with great shape and design. Lighter weight, but warm, soft, comfy and in amazing shape! A few small pulls, but they should be fixable. 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) 22"
Shoulder to end of sleeve (including cuff) 19"
Length 22"

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