International size equivalents are for reference only. For the best fit, choose your JEC size based on your bust and hips. Our maternity pieces are designed with room for your growing bump and for postpartum wear too. If you're between sizes, check the individual product page for whether to size up or down.

Find your fit

Because your body deserves to feel comfortable at every stage.

For the best fit, take a few simple measurements while wearing a fitted top or bra. Keep the tape comfortably close to your body - snug, never tight.

Bust
Measure around the fullest part of your bust.
Waist
Measure around your belly button, or the widest part of your bump.
Hips
Measure around the fullest part of your hips.

Expecting?

Your body is changing, and that's exactly what it's meant to do. Our maternity pieces are designed with room to grow, so you generally don't need to size up just because you're pregnant.

Nursing?

Use your current bust measurement, not your pre-pregnancy measurement, to find your best fit.
