Vintage Long Sleeve Shirt by JC Penney

Here is an awesome vintage shirt from the 1970s by JC Penney. Most likely polyester or a poly blend. Handsome blue fabric with that amazing 70s terry cloth feel. Two button collar and a pocket on the left breast. It's medium weight, soft, comfy and in amazing condition with years of life left. The tag says XL, but here are the exact measurements, taken laying flat. (please refer to the last pic to see how I measure shirts)

Chest (armpit to armpit) 24"

Shoulder to end of sleeve (including cuff) 24"

Length 27"
