Onesie Size Guide
Our onesies are made of comfortable stretchy fleece so they are easy to size. The most important sizing criteria is height. To help you, we have provided an approximate height range. If in doubt take the next size up. Onesies are designed for an oversized fit and are much more comfortable that little bit bigger.
