Arriving October 2026.

Meet the bikini bottoms you'll actually want to wear. A classic mid-rise shape with medium-to-full coverage and a clean line that sits smoothly across your tummy and hips without digging in or riding up. 360° power mesh gives you that held-in, supported feeling, while extra coverage through the front means you can actually move, swim and sit down without constantly checking what's on show. Full coverage through the crotch. No wedgies and no worries, she's classic for a reason.

- MID WAIST - mid-rise coverage with a smooth, compressive feel through the midsection for a flattering, held-in fit
- COMPRESSION - 360° power mesh for a supported, held-in feel without the squeeze. Especially good if you're postpartum or looking for extra support through the midsection
- COVERAGE - medium-to-full bum coverage with a medium leg line, plus more front coverage than most bikini bottoms
- FABRIC - Ultra matte Luxe Crinkle fabric for chic finish
- SIZE RANGE - XS-2X (Australian sizes 8-18)

The bikini bottoms you reach for without thinking twice. Classic, comfortable and made to stay put. Because your bikini bottoms should be the last thing you have to think about.

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.

Classic for a reason

Shape wear, but make it swim. These bottoms you'll reach for on repeat. No wedgies, no gaping and no second-guessing what's on show. Just the bottoms that quietly do their job so you can get back to your day.

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.

This is the first bikini I have worn since having my daughter four years ago! I feel so confident in this, and paired with the All Day Bikini top it is *chef’s kiss*

This is the first bikini I have worn since having my daughter four years ago! I feel so confident in this and I love that you can slide the toggles up and down to create a different look. 4 stars instead of 5 because I personally would like the band to be a bit wider (maybe double the width) to keep side boob/back fat contained - mine is particularly adventurous ;)

This is the comfiest bikini I’ve ever worn. The fabric is of such high quality and looks so flattering on. It also felt SO GOOD not having to constantly adjust my straps and pull out wedgies!

Last year I made my first Fearless purchase, the Adventure Suit. I had followed Lyndi’s journey via Socials. I loved her enthusiasm, seeking product feedback and her goal to help all women feel great about themselves. I’m not great at online shopping but I believed in Lyndi and her passion. I love love my adventure suit. Fast forward to 2026 and I have just purchased my first bikini!!! My first bikini since I was probably 4 years old. I am even happier with my Fearless All Day Bikini Top and Bottom. I never thought I’d have the confidence to try a bikini, but I trusted Lyndi and Fearless. Thank you thank you

The fit and material are great, but I really dislike the type of clasps that are used for the straps and the main bikini band. I find they never stay in the right place and come undone so easily. I wouldn’t have bought this top if I woukd have known that.

Love these bikini bottoms. They feel firm and comfortable with excellent bottom coverage and don’t ride up. I haven’t ever bought swimwear online, but I’m so pleased I took a chance on Fearless and got them as they’re better than any bikini bottoms I’ve ever owned. The sizing chart was spot on.

Love my new all day bikini, very flattering and comfortable on my postpartum body. So excited for this summer, not going to be hiding in board shorts and tshirt (or my old maternity bathers). I swapped my original purchase for a different size and this was such a quick and easy process, thank you!!

This is simply THE BEST bikini you could buy. Strong, supportive, compressive fabric but totally comfortable enough to stay in all day!!!! Not to mention, this company is run by the most awesome couple who genuinely care about the experience of ALL women and I know they will be striving to keep growing and improving Fearless 🫶🏼🩵

Honestly was skeptical about buying a bikini but gosh you've proved me wrong. I absolutely love the level of support on these.

Compressive, great fabric, very flattering and super comfortable. Coming from a 4 months postpartum mum of 2 who was dreading going to the pool. I love these bottoms, they are fabulous. Everything I wanted, just as advertised, PERFECT.
