The high-waisted bottom that stays exactly where you put it.

More coverage and more support = more confidence to actually get on with your day.

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.

Feel Feminine and Supported

A high-waisted bottom should feel like a choice, not a compromise. The Side Tie High Waisted Bottom gives you coverage and compression without the dig, the roll, or the constant readjusting. Pull the hip tie tighter for more coverage, looser for less, or wear it done up in a bow. We want you to have the choice on how much skin you show.

Why You Can Trust Our Sizing

We surveyed 15,000 women before designing a single item and we're still listening.

Every item is fitted and tested on two sizes - a 10/12 (C-Cup) and a 14/16 (E-Cup) - then trialled on real women in their 20s to their 60's. Because no two bodies are the same.

When our fabric ran small, we changed the sizing. Feedback beats data, every time.

Sizes XS-3X. Built for the body you actually have.

Still Not Sure?

Finding a swimsuit that actually sculpts, supports and survives the ocean without a wardrobe malfunction? We used to think that was a myth too. Don't take our word for it - real women are already raving about the fit, the comfort and the "wait, this actually works" confidence Fearless delivers.
