i only have a metal tape measure, so it's hard to get the exact measurement around the neck about 12 to 13inches, about 7 inches from the armpit to the bottom, from the tip of the sleeve to the bottom about 10 1/2 inches, so don't quote me exactly,,this suit would never fit a german sheppard sized dog that would be size large, a toy poodle would wear a small, this one is a size medium
