Silk, Cindy Moon, bodysuit for cosplay. worn once to LA comic con. Size is kids large so the equivalent is XXS in women. Zips up from the lower waist in the back. See pics with measurements. I bend the bottom part because that's where the heel is supposed to be. Leg measures 23 inches. Chest is 12.5 inches across. Arm is 19 inches from shoulder to wrist. The costume has some stretch.
