Here is an awesome vintage T-shirt by Locker Tops. 50/50 cotton and poly blend, and made in the USA. Bright red shirt with slight V neck and black and yellow accents. Almost has the look of a sports jersey. Fairly light weight, sheer, super soft, comfy, and in amazing condition with tons of life left. 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) 21"
Shoulder to end of sleeve (including cuff) 11"
Length 26"

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