Size Guide


Continue to enjoy the beach as your bump grows wearing our Mama Bikini Pant. With the same supportive waistband and beautiful compression fabric as our bestselling Mama Tights, you will feel comfortable and supported through every trimester.

The shape-retention fabric grows with your bump so you can start wearing it as soon as your regular swimwear becomes uncomfortable. The wide waistband can be worn over the bump for support and sun protection, or rolled down over your hips.

This brief can also be worn under your regular clothes, like summer dresses, for additional support to promote core stability and reduce pregnancy aches and pains.

Pair with any Active Truth crop – like the Flow Crop.

We always recommend using your measurements to find your perfect fit. Number sizing differs so much between brands that it's difficult to calculate on that alone. In our experience if you are between sizes or unsure then it's best to size up.


  • Exposure to chlorine will damage your swimwear. It is essential that you rinse immediately after use and cold gentle machine wash in a delicates bag to remove all traces of chlorine
  • Use mild detergent
  • Do not wring or soak
  • Drip dry in shade. Don’t tumble dry
  • Do not leave rolled up wet
  • Avoid contact with rough surfaces as this may cause pulling to swimwear
  • We recommend that you avoid wearing your swimsuit in spa baths
