I don't know how to measure cloths, lol..it's 10 1/2 inches long from top of to bottom and from the bottom of the armpit across to the other armpit is about 21 inches wide.
26 inches from the top of the sleeve to the bottom, lol..I don't know where I got 10, I think it was suppose to be 20 1/2 from the neckline to the bottom, thanks for the update.
