Here is a beautiful short sleeved shirt, “Something Special” by Gino Fabrini. It’s probably 100% Polyester. It’s an off white shirt with almost a silverish tint to it, and cool little designs that are kinda dandelion in nature, in orange/brown. The tag says 15 1/2. Click the photo for more info.
Here are the measurements when laying flat:
Shoulder to end of sleeve (including cuff) 10.5″
Chest (armpit to armpit) 22″
