Finding your perfect fit matters.

Below you’ll find the size guide to help you choose confidently.

Hatch is a US maternity brand. Your pre-pregnancy size is the best starting point to find your size at HATCH (after all, no one knows your body better than you).Size up for a more relaxed fit or down for a more bodycon look. If you're 5'2'' or shorter our Petite (P) sizes are for you - above 5'2'', choose O/S.

If your bust or hip size puts you between two sizes we recommend you go with the larger of the two - so if your bust measurement puts you in a size 2 but your hips are more in line with a size 0, go with the size 2.

Our maternity sizing estimates a standard weight gain of 25-30lbs.
