Measures Approx:

Total Length - 29 inches

Arm Pit to Arm Pit - 22 inches

Shirt overall doesn't look like it was worn much at all!  

It actually is possible it may never have been worn.  There is a couple of spots on the front but due to the fabric feeling like it hasn't seen a washing machine, I didn't want to take that away with a washing.  Very cool piece and very hard to find.
