Pet Couture vests come in five sizes — X-Small, Small, Medium, Large, and X-Large. To find the best fit, measure your pet's neck and chest (the widest part of their chest, just behind the front legs) before ordering. All measurements are in inches.
XS is designed for a neck under 16" and chest under 17". Small fits a neck of 12"–21" and chest of 14"–23". Medium works for a neck of 14"–23" and chest of 16"–25". Large fits a neck of 16"–25" and chest of 18"–32". XL is best for a neck of 18"–27" and chest of 20"–40".
The velcro closures allow for some flexibility in fit, but getting as close to your pet's actual measurements as possible will ensure the most comfortable wear. If your pet falls between sizes, we generally recommend sizing up.
