  • Smart adjustable bust sliders
  • Flattering cut with a peek of side bust
  • Elasticated, adjustable straps (wear straight or crossed)

The All Day suit also doubles as a sexy, sleek bodysuit (thanks to its ultra-matte, ultra-flattering recycled fabric).  

Fearless Swimsuits are designed for everyday women (not size 0 mannequins), then tested on 150+ real bodies.

That's why she’s so comfy, timeless, and built to last. 

Fabric & Care

This swimsuit is made from a ultra-matte smooth fabric, so it doubles as a bodysuit (= twice the wear from one purchase!)

Outer: 75% recycled nylon, 25% elastane
Lining: 86% polyester, 14% elastane
Power mesh: 72% nylon, 28% elastane

Sustainability isn’t just about recycled fabric. It's buying a high quality product that lasts for seasons. Caring for your Fearless swimwear will help you get mileage from it.

Here are our tips:
  • Rinse in freshwater after wearing, especially after wearing in pools or spas
  • Cold hand wash or gentle cold cycle
  • Don’t tumble dry, bleach, soak or iron
  • Dry in the shade

Then go have a nap ‘cause doing laundry sucks
