For leggings, the hip measurement is the most important for finding your perfect fit, especially if you're between sizes.

 

Hip: the widest part of your hips making sure the tape measure is even over your bum

 

Waist: your natural waistline above your belly button and below your rib cage

 

Bust: the fullest part of your bust at nipple level

      For maternity leggings, the hip measurement is the most important for finding your perfect fit.

       

      We've designed our pregnancy leggings with plenty of room for your growing bump, so don't use your waist measurement.

       

      Hip: the widest part of your hips making sure the tape measure is even over your bum

       

      Waist: your natural waistline above your belly button and below your rib cage

       

      Bust: the fullest part of your bust at nipple level

       

       

      Crops

      Due to the changes your body experiences during breastfeeding, we recommend comparing your under bust measurement (where your bra band sits) to the sizing chart below.

       

      Our nursing crops cater up to a DD cup. For larger cup sizes you may wish to size up.

      What makes the Esperance work

      One shoulder, real support

      One shoulder, real support

      Plenty of rise through the shelf bra holds a bigger bust, with no spillover on the strapless side.

      Moulded cups, no lopsiding

      Moulded cups, no lopsiding

      Sewn-in moulded cups and a panel under the bust lift B to G cups evenly. No inserts to twist or lose.

      An elasticated top edge keeps the neckline in place. Chlorine resistant with UV 50+.

      Ruching and power mesh

      Ruching and power mesh

      Signature ruching and internal power mesh smooth through your tummy.

      your questions, answered

      What women ask us most about the Esperance.

      Esperance fits true to size and comes in sizes 6 to 26. If you're between sizes, go down. The built-in shelf bra supports B to G cups, so you don't need to size up for a bigger bust.

      Size Guide

      Yes. A shelf bra with sewn-in moulded cups and a supportive panel under the bust lift B to G cups, with plenty of rise so there's no spillover on the strapless side.

      Yes. An elasticated top edge keeps the neckline in place as you swim and move.

      The strap sits on your right shoulder. It's a fixed strap, so it doesn't adjust.

      Because the strap is fixed, we don't recommend Esperance for a long torso. Try the Long Torso Coolum, with 7.5cm of extra front body length.

      Shop Long Torso swimwear.

      Yes. Moulded cups are sewn into the shelf bra, so they shape your bust and never twist or go missing in the wash.

      Yes. There's space in the shelf bra to hold a breast prosthesis or breast form, and there's no underwire to press on sensitive areas.

      Yes. All Active Truth swimwear is made from chlorine-resistant fabric, so it's built for pool laps, aqua aerobics and regular swims.

      Yes. All our swimwear is rated UV 50+.

      We offer exchanges to help you find your perfect fit and accept returns for 30 days from the date of purchase. Returns for refunds are only available for items purchased at full price.

      Items marked Final Sale can't be refunded, returned or exchanged. See our returns policy.

      Yes. Shipping is free on orders over $200.
