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.

      jacket
