Here is an awesome vintage t-shirt by Velva Sheen. 50/50 blend of cotton and polyester, and made in the USA. Black shirt with great graphics on the front and back. Fairly thin, light weight, soft and comfy. It's in excellent shape with tons of life left! The tag says Adult 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) 18"

Shoulder to end of sleeve (including cuff) 8"

Length 24"

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