The Happy Belly Bikini Bottom


by Mother and Sun



The Happy Belly bikini bottom sits under the pregnant belly, making it perfect for mamas with pelvic pressure or who like to have their beautiful bump on show. It’s also a great option for Caesarean mamas as it won’t put pressure on the scar area.


  • Scooped front to sit below the belly or c-section scar.
  • Flattering fit around the butt.
  • A contrast band to add a little razzle dazzle.
  • An exclusive print made just for Mother & Sun mamas (print placement may vary).
  • The most deliciously soft yet durable fabric made from recycled plastics (have you heard we’re really sustainable? Head here to learn more).
  • Oh yeah, it’s also fade, pilling and Chlorine resistant with UPF 50+ protection and shape retention.

We totally get that sizing during this stage of your life can feel rough. We’ve also designed the products with your changing body in mind.

So, with this garment we recommend you size up. That’s because the design has firmer stitching and less give. Also, check out our sizing guide here. And get some piece of mind by reading our returns page here.

Our models are wearing Size 8. Our gorgeous pregnant model was 28 weeks in the photos.
