Here is an awesome vintage T-shirt by Collegiate Pacific. 100% cotton and made in the USA. This was locked away in a trailer in 1988, and untouched until 2016. It is new/old stock, and has never been worn! I'm no expert on CP tags, so this could be from the 1970's, but I'll call it 80's. Dark blue jersey with gray accents and Georgetown Hoyas graphic on the front. This one is in mint condition. Soft, comfy, and ready to finally live it's life after being locked up for 30 years! The tag says Medium 38-40, 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 29"

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