Vintage Big Brother T-Shirt by Tee Swing
Here is a great vintage kid's T-shirt by Tee Swing. 50% kodel, 50% cotton, and made in the USA. Light blue shirt with wonderful graphic on the front in red. Super soft and comfy, and it's in amazing shape with tons of life left! The tag says Medium, but here are the measurements taken laying flat (please refer to the last pic to see how I measure shirts)
Chest (armpit to armpit) 13"
Shoulder to end of sleeve (including cuff) 4"
