Arriving early July 2026.

The Side Tie High Waisted Bottom was designed for women who want coverage, comfort, and a no-dig waistband. A built-in tie sits at the waist so you can adjust the fit to your body - wear it in a knot or bow. Either way, it sits exactly where you want it, with zero digging, zero rolling, and compressive support through the hips and midsection.

• ADJUSTABLE TIE WAIST - no-dig design, wear as a bow or a tie for a customised fit
• HIGH WAIST - high-rise coverage with a smooth, compressive feel through the midsection, ideal for women who want tummy control in a bikini bottom
• COMPRESSION - 360° power mesh for a snatched, supported, held-in feel
• COVERAGE - medium-to-full bum coverage with a medium leg line
• HARDWARE - brushed gold Fearless hardware for a polished finish
• FABRIC - chlorine-resistant Luxe Crinkle fabric (chlorine resistance 4/5)
• SIZE RANGE - XS-3X (Australian sizes 6-20)

Fabric & Care

This swimsuit is crafted from our high quality LuxeCrinkle fabric - made using recycled plastic bottles and pre consumer waste. Soft, supportive and planet friendly.

Outer: 84% recycled polyamide, 16% spandex
Lining: 75% recycled nylon, 25% spandex
Power mesh: 85% polyamide, 15% spandex

Sustainability isn’t just about recycled materials - it’s about choosing well made pieces that last season after season. With the right care, your Fearless swimwear will keep looking incredible for years.

Care Tips:
  • Rinse in fresh water after every wear, especially after pools or spas
  • Cold hand wash or gentle cold cycle, separately, to prevent colour transfer
  • Avoid tumble drying, bleaching, soaking or ironing
  • Dry in the shade

Then go have a nap - because laundry is the worst.

FAQs

Does this bottom run true to size?
Yes. Choose your usual size based on our size guide. If you're unsure, size up.

Is it cheeky or full coverage?
Medium to full coverage with a medium leg line - enough to feel confident, not so much that it feels like a board short.

Does it dig in?
No. The waistband is designed to sit smoothly without cutting in - zero digging, zero rolling.

Is the fabric compressive?
Yes. The Luxe Crinkle fabric is smoothing and supportive with 360° compression through the hips and midsection. You should feel held and comfortable - firm but never tight.

Is this good for tummy control?
Yes. All Fearless styles feature built-in 360° power mesh compression designed to smooth, sculpt and support - without digging in or rolling down.

Will it stay in place all day?
Yes - and this is what customers rave about most. The compressive fabric keeps everything exactly where it should be through pool days and beach activities. No wedgies, no adjusting.

Are colours true to photos?
Yes. Colours are photographed in natural light, though slight variation can occur depending on screen settings.
