Here is a sweet long sleeve sweater by La Vista. Feels like an acrylic blend, made in the USA. Great geometric design in gray, white, black, and red. Warm, soft, comfy and in amazing shape! Here are the measurements. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 20"
Shoulder to end of sleeve (including cuff) 19"
Length 23"

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