      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.

      A Rare Occasion

      "What a terrific surprise when my Coolum swimsuit arrived. It's hard enough to get a good fit when ordering clothes online; but I had felt a swimsuit was going to be a big ask. However, the Coolum delivers well and truly. . . . a lovely fit and flattering design."

      Margaret W. (5/5)

      Been Looking For These!

      "I bought this pair in an XL. They were a little loose so decided to purchase the size smaller. Thank goodness there was a sale on. Much better clingier fit even though I used the measuring information for the first pair. Haven't swum in them yet. Waiting for their first dip in Bali, early October. Love the design as they don't make me look like a frumpy old woman. And I can say that as I am in my senior years. 😜"

      Jenny T. (5/5)

      Fabulous swimsuit on. Excellent stomach

      "Fabulous swimsuit on. Excellent stomach control panel and the sizing is accurate and it fits really nicely. The fabric is thicker than I am used but that means it will last and continue to hold its shape well for many seasons. The only downside is for us less endowed there is no padding as the designer made these for ladies with a decent chest. Personally I could use a bit of reinforcement. :) That aside I would buy another pair in a heartbeat."

      Elizabeth D. (5/5)

      The perfect fit.

      "These bathers are the best bathers I have ever worn. They fit perfectly. I’m a size 14e and bought 12 to 14. They are a bit high cut but look amazing and a very comfortable. I’m sitting in Bali right now by the pool in the Ubud jungle. I will order another pair."

      Swimwear

      "I usually would not buy swimwear online, I was dubious about the fit and quality. I have to say that I really do like these swimmers, however I have not worn them yet, I bought them for an overseas trip soon. Love the colour, the fit is really good and true to size and nice material."

      Lynne P. (5/5)

      Lovely Quality

      "I am pleased with my purchase, especially at a sale price. As it is fully lined, it feels secure as a senior purchaser. As an older person, however, I would like to see some more coverage of the lower buttocks (maybe as an option on some colours)"

      Leigh B. (5/5)

      Perfect!

      "I was skeptical that any bathers could be so good, but purchase on sale and honestly- they are excellent. Good bum coverage, breast support and Tummy support. Feel comfortable and look great, will definitely order more and recommend to friends."

      Taryn P. (5/5)

      Now I have the Coolum one piece in 3 colours

      "I ordered the Coolum one piece initially in brown and now have it in 3 colours. I love the style, the fit and the fabric. There are so many nice colours it’s hard to choose, so it’s only a matter of time before I fill my cart up again."

      Leanne T. (5/5)

      Coolum truely are the Best fitting swimmers

      "I saw the reviews on line and thought why not! I got one pair they were the best swimmers I’ve ever felt comfortable in - so I’ve now gone and got 4 pairs in different colours! They are double material firm but with some give. You won’t regret!"

      Melissa R. (5/5)

      Best swim suit I’ve ever owned!

      "This is my second suit I loved it so much! The quality and texture of the fabric is outstanding, the design and fit are flattering - I’m no longer intimidated by summer arriving and putting on my bathing suit and going to the beach!"
