Arriving October 2026.

Low back with a high impact. This is the one-piece you wear when you want a little more skin, a little less coverage and absolutely no intention of blending in. The deep scoop back does the flirting, while light compression smooths everything else out. A shelf bra and thin moulded cups give smaller busts (A-D cup) a little shape without trying to turn this into a high-support swimsuit. Basically, it's doing the most in all the right places.

- SUPPORT - ultra-low back makes this a lower-support style, designed for smaller busts (A-D cup) rather than high-support needs
- NECKLINE - scoop neckline with a shelf bra and thin moulded foam cups for light shaping
- ADJUSTABLE - adjustable back straps for a more personalised fit
- TUMMY CONTROL - compression that smooths and supports without squeezing
- COVERAGE - medium leg rise, medium bum coverage and fully lined
- FABRIC - chlorine-resistant Luxe Crinkle fabric, chlorine resistance 4/5
- HARDWARE - brushed gold Fearless hardware for a polished finish
- STYLING - wears as a one-piece or doubles as a bodysuit beyond the beach
- SIZE RANGE - XS-L (Australian sizes 8-14)

This is the one-piece for when the back is the outfit. Wear it with nothing but sunscreen at the beach, then throw on jeans or a skirt and keep going. It works for swimming, lunch, holidays and whatever happens after.

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 have underwire?
No. The scoop neckline is finished with thin foam cups and a shelf bra for light shaping - the low back means less structure through the bust, so this is a lower-support style rather than an underwire one.

What bust sizes does it suit?
Best suited to A-D cup, smaller busts. The scooped back is the whole point of this style, which means it trades some structure for that silhouette.

Is this a high-support style?
No, and we would rather tell you now than have you find out at the beach. The Low Back One Piece is built for a statement silhouette, not maximum hold - if you need higher support through the bust, look for one of our shelf-bra or underwire styles instead (Braveheart lands in the same October drop).

Does it run true to size?
Yes. Choose your usual size based on our size guide. If you're between sizes, size up.

Are the straps adjustable?
Yes. Adjustable back straps let you fine-tune the fit through the shoulders and back.

Can I wear it as a bodysuit?
Yes. The Low Back One Piece doubles as a bodysuit beyond the beach - pair it with jeans or a skirt and that statement back keeps working.

Is it good for tummy control?
Yes. Compression through the midsection supports without squeezing.

What's the coverage like?
Medium leg rise with medium-to-full bum coverage, and fully lined throughout.

What's the fabric like?
Chlorine-resistant Luxe Crinkle - 4/5 resistance rating, so it holds its shape and colour wear after wear.

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

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.

Great quality swimsuits and amazing customer service! Would definitely buy again ☺️

I like the colour but i can see the lining perhaps its - just the wrong fit. I also should have paid more attention to the chest sizing as the shelf bra is very large and does not suit my small chest. It will be good for laps in the swimming pool though. Definetly a sporty style

Caitlin v (New Zealand)

I love this swimsuit. I feel super supported up top, covered on my bum and sucked in on the tummy. I wear it ALL the time with shorts or a skirt and it looks so cute. Only issue is the sizing, I ordered a large after reading lots of reviews (normally a size 10) and it's the perfect size, I never wear a size large so the sizing is definitely off.

Peta Nash (Australia)

I was worried about the torso length as I’m under 150cm tall and a size 12 but it is perfect. The compression is just right and not uncomfortable at all. I highly recommend you try

Really happy with my purchase great quality

Jennifer H. (Australia)

Love the fit of this suit (my second fearless suit!). It is so supportive in all the right places!
Only problem is, when I went in the water, a huge air bubble got stuck in the top band of the suit. It looks like I have a floaty on or something. As a big busted girl (10E) I don’t love the extra attention it draws. I also haven’t had a swimsuit do this before.

S
Sarah Rhymes (Australia)

So happy! I originally order a M based of measurements but exchanged for a L and so glad I did! Fits so nice. I have a small bust and it doesn’t feel to roomy. The best thing is that it didn’t go big and baggy in the water some some suits can! The long torso is a GAME-CHANGER!! Won’t be my last purchase. THANK YOU FOR YOU HARD WORK!

D
D. (United States)

Loved the colour and compression! The fabric around the neckline/bust area was slightly loose, perhaps I could have gone down a size. Overall though I’m very happy with my swimsuit. I feel confident & absolutely love the bum coverage.

L
Leora (Australia)

Love my one piece! It holds me in the right places and is super comfortable to wear. It gives me better support than my compression wear. I have no doubt I will be wearing it instead. I accidentally ordered the wrong size and the team were wonderful to deal with. Absolute legends

You feel so secure in these bathers. They hold you in tight in all the right places. Very comfortable. I feel very confident when wearing these bathers.

I love my suit ! It’s for the pool not the sun (Scottish weather :) I love the whole ethos behind this and that it’s a company actively telling me that my body is ok. I have a disability and my confidence can be low, this suit is set to get me back in the pool. I think these things may feel small, but can be life changing. The fit is good (had to exchange med for large as a UK size 12) It is a wee bit of a wiggle to get it on but have practiced and all good. Love the fit and love the colour. Thank you 🙏

Emily S. (Australia)

I absolutely love this swimsuit! I was a bit concerned about how tight it felt when pulling it on over my hips…but after a bit of a wiggle, it slides on and fits perfectly. I am 5ft 11 so I got the long torso option. It’s great - doesn’t feel like it’s pulling down on my shoulders at all. Love love love! ❤️

P
Post as anonymous (Australia)

I am in love. First try on I was worried I wouldn't get it over my hips but once on... amazing!!
I love the straight neckline and as a girl who is 5'10' I've always struggled with one piece suits dragging down my shoulders but this one is just SO comfy!

L
Leora

Love love love this suit! I accidentally ordered the wrong size and luckily noticed before it was shipped. Within 5 minutes of sending fearless a message the order was fixed and problem was solved. The team and customer service cant be faulted!
The suit it self is brilliant! I love the thick material and how it holds everythibg in. I have no doubt it will double as shapewear too!
Will definitely be ordering another style!!

Such a great fit! Crazy how swimmers that actually fit can make you feel great! Will be buying more!

Stephanie Wilkie (Australia)

Feels amazing, I can't believe something that is pretty compressive can also be comfortable. I have no idea how those thin straps could hold up my large boobs and it feel ok- it somehow works! Tummy felt good, length felt good. Was not too long at all.

A
Angelica Pupillo (Australia)

I couldn't love these more!!! The whole experience from seeing the story online, to the thoughtful packaging and the amazing swimwear itself!! The fabric is soft and really holds your body together making it the perfect bathing suit for diving under waves in! The cut is also perfect, I will totally be wearing this as a body suit too!! Love love love 10/10!

Love this one piece! It’s so flattering and comfortable. Love the tummy control and the colour range for this swimsuit is awesome. Can’t wait to purchase another!

P
Post as anonymous (Australia)

Absolutely stunning! Also incredibly versatile! I could totally wear this with some jeans and use it as a body suit for the day and hit the beach in the afternoon without having to worry about packing swimmers or changing! The compression of this is a life changer!

S
Steph (Australia)

Honestly it’s even better than I imagined!! Postpartum mum x 3, mum belly, long torso. It ticks so many boxes! I feel so held in and the bum coverage is great!! Imagine spanx but make it swim without feeling restricted. The option of long torso is a game changer for me :) I can’t wait for a summer where I don’t have to constantly adjust my swimmers! Really is worth the money!

C
Caz (Australia)

Overjoyed I have found a snatched in, forgiving one piece to fit my long torso, curvy, E-cupped mum bod! This is a beautiful piece with thick confident material to keep you safe from the surf and looking smooth and confident. Can’t wait to jump in the water!
