      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.

      Perfect Bali bathers for swimming and non-swimming activities!

      "Wore these daily on my holiday in Bali, both as swim wear and outer wear. The fit, padded cups, longer length and seamless coverage made it the perfect summer holiday top paired with shorts or skirts when I was out and about. I will definitely be wearing it often this summer and beyond. Would love slightly thicker straps for comfort. My only issue is it doesn't come in size 14-16, so I had to upsize. Please consider adding this size to the range. Thanks!"

      — Chenoa O. (5/5)

      Perfect for me

      "I purchased this after purchasing the one piece bathers. Originally purchased size M 10-12 but needed L 12-14 for better coverage for the bust. The wider straps are so good, soft & no digging in. Haven’t worn yet but looking forward to summer!"

      — Valerie R. (5/5)

      Perfect swimming top

      "This is a perfect top as I love the one piece, but find the bottom too revealing, I use this top with a bottom from another brand. Love the thin straps and bust support, whilst the gathers on the side and mesh hide and smooth my tummy."

      — Carol L. (5/5)

      Tankini

      "Fantastic product. Love the fit and feel. Very comfortable but still looks great. I’ve bought more already. My only complaint is that they don’t do the tankini in all the colours they do the costumes in!"

      — Suzanne D. (5/5)

      Great fitting tankini top

      "Cut and ruching provide a flattering fit! I wear a AU size 16C bra and bought the XL which fitted comfortably around the chest and waist. But I am a bit short waisted. Am 163cm tall. And the length was too long so paid a seamstress to take it up ($25)."

      — Karen S. (4/5)

      Great two piece. Gift idea

      "I had purchased bathers and loved them. Trying to get my daughter interested. So… guess what she got for a birthday gift. She loves them. Can see her confidence when she wears them. Two piece but looks like a one piece. Great versatility."

      — Leah S. (5/5)

      Best tankini top!

      "The fit is great, they look so flattering, The textured fabric and colour is lovely, excellent length for coverage, and they hold in all the right places. The adjustable straps are a great addition."

      — Siri C. (5/5)

      Great purchase

      "The tankini is long in the body with good stretch and style. The textured fabric adds is lovely. The tankini goes well either way the Coolum bikini bottoms."

      — Jane B. (5/5)

      The best

      "This is by far the best swimsuit I have bought Love the fit I am 71 and always been self conscious in a swimsuit but this is actually flattering on me Love it would absolutely recommend"
