The shirt measures 23 inches from armpit to armpit laying flat so I think that would make it a size 46. The sleeves are 26 inches from armpit to end. The pants seem to have a 39 inch waist and the leg length is 29 inches. Everything could use a good dry cleaning. This came out of the estate of a Civil War Confederate Reenactor in Charleston, SC.
The suspenders are pliable and useable. The item "CIVIL WAR REENACTORS RED ARTILLERY SHIRT AND BLUE PANTS & SUSPENDERS 39 WAIST" is in sale since Sunday, October 24, 2021. This item is in the category "Collectibles\Militaria\Civil War (1861-65)\Reenactment & Reproductions\Uniforms".
