Swimsuit
A supportive one piece swimsuit for women with a larger bust who want sculpting and coverage without the discomfort. Because swimwear should feel good on your body, not just look good in theory.
Fabric & Care
This swimsuit is crafted from an ultra matte, silky smooth fabric - so sleek you can style it as a bodysuit too. (Double the outfits from one purchase!)
Outer: 75% recycled nylon, 25% elastane
Lining: 86% polyester, 14% elastane

FAQs
Yes, this style runs true to size. If you're between sizes we always recommend going up a size.
Is this suitable for a long torso?
Yes. We offer a Long Torso option in our red, black and blue colours, designed to give extra length through the body without pulling on the shoulders or riding up.
How supportive is the bust?
The All Day One Piece offers medium support with internal structure. This style does have a slight side boob look to it, so keep that in mind!
Is the fabric compressive?
Yes. The fabric is firm, smoothing and supportive - designed to feel like high quality active wear. Comfortable compression.
Is it cheeky or full coverage?
Bum coverage is full and designed to sit on the hip.
Are colours true to photos?
Yes. Colours are photographed in natural light, but slight variation can occur depending on screen settings.
Does the All Day One Piece have strong tummy control?
Yes - it features 360° power mesh compression that sculpts the tummy and delivers a held-in, supported feel from all angles.
Is the All Day One Piece suitable for larger busts?

What's the difference between the All Day and Adventure One Piece?
The All Day features 360° power mesh compression for stronger shaping and sculpting. The Adventure offers medium compression - great for active days and movement.
Will this swimsuit actually fit my body type?
Based on 35 five-star reviews, this suit delivers the rare experience of finally finding swimwear that actually fits - including customers with long torsos, pear shapes, larger busts, and post-pregnancy bodies who typically struggle with swimsuit fit. The adjustable straps mean you can customise the fit for your unique body rather than settling for a one-size-fits-all approach.
Does it provide enough support without feeling restrictive?
Customers consistently report incredible support for bust, tummy, and post-pregnancy bodies that feels compressive yet comfortable - not restrictive. One customer confirmed support is incredible when dry and wet, and reviewers describe it as “hugging you in all the right places” with the most flattering cut.
Will it stay in place during active beach days?
Yes - reviewers report the All Day suit stays put during surfing, playing with children, and active beach activities without constant adjustment. Customers specifically mention it maintains its position during movement, so you can focus on enjoying your day rather than managing your swimsuit.
Is the quality really worth the investment?
With a perfect 5.0/5 rating across 35 reviews, customers consistently describe this as the best swimsuit they’ve ever invested in. Reviewers highlight the luxurious texture, premium matte fabric, and multi-use value - many wear it as a bodysuit for casual outings, getting multiple garments in one purchase.
How will I actually feel wearing this?
Customers express overwhelming emotional responses - words like “gorgeous,” “confident,” and “amazing” come up again and again. Reviewers report feeling better than ever before in a swimsuit, with one long-time cover-up wearer who spent decades hiding in shirts and rashies now wearing this suit confidently without layers.
Can I really wear this beyond the beach?
Yes - multiple reviewers confirm the premium quality and design make it versatile enough to double as a bodysuit for everyday wear. Customers report pairing it with jeans, shorts, or casual bottoms for non-beach outings, and one reviewer took hers directly to the sauna and felt gorgeous and comfortable in that setting.

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.

This suit absolutely gave me confidence. The way it fit like it was made specifically for my body was crazy!!! I am 5’9 160lbs I’m a C/D cup with wide hips
My one key tip to getting the correct size is MEASURE YOUR BODY!!
I bought a medium based on my measurements,if I would have based strictly on sizing numbers I would have ended up with an XL
I love this brand.I love these swim suits. Highly recommend
This is a great swimsuit, way better than any high street ones I’ve tried
I have a long torso, it fits well but for me maybe could do with a bit longer. I must be super long.
I’m 5’10’’, 40D bra and uk 16-18
I’m 4 months postpartum and I love the hug it gives the tum and it’s easy to breastfeed in.
If I had to be picky I would prefer the back to be higher to support the back fat and a bit more support in the bust with the strip under the boobs being tighter
But all in all ill be having a great many summers in this suit and can’t wait to purchase one of the new styles
Love shopping with Fearless. From the emails to the instagram ads and website it makes me happy. Very slick experience that makes me feel loved and seen. How that is possible is remarkable.
I can’t actually begin to describe what it feels like to follow a company from its first moments, share the ups and downs via Instagram, wait with baited breath while its owner shows us each sample as it arrives, receive my password to the very first line drop on site, then actually WEAR the swimsuit I’ve always dreamed of.
This label have DARED to challenge an entire industry’s idea of what we SHOULD look and feel like in our swimmers, and I am proud of them even though I’ve never met them! I’m a customer for life now, no going back, ever.
I’ve been eyeing off these swimsuits for a while now, and took the plunge in the recent sale. There was a slight issue with my order, which was immediately sorted by the team who were fabulous.
Now the suit itself, perhaps because of my long torso/shape I didn’t really have to ‘jiggle-jump’ into it, but boy did I feel supported anyway! This is so amazing for a mum of four, including twins, with a ‘jiggly tummy pooch’ as my kids love to tell me!
Definitely would recommend this suit to others. It left me confident enough to chase my kids around the resort on a recent holiday without a cover-up on. Well done fearless team!
For reference- I’m 167cm/12DD (bust 99cm/hip 104cm, Au size 12-14) and bought a Large/long torso.
Super easy to use and great options!
To be honest I wasn’t hopeful when I ordered. I’m bigger busted (14H-HH) and buying swimsuits online has generally resulted in disappointment. Not this time though! I LOVE the colour, the fit and the quality of this suit. It’s sexy but not too sexy. The red definitely give Baywatch vibes.
I got the long torso option (which surprised me as I don’t consider myself to have one!) and the fit is perfect.
Highly recommend measuring yourself prior to ordering and taking advantage of the sizing tool offered on the site.
For reference I’m 165cm, usually wear size 16 clothing and I ordered a 2XL in the fearless suit.
Amazing swimwear, fits body and boobs nicely especially for a smaller boob gal, love the material, hugs the body, smooth, elegant, best swimmers ever will be buying again
My order arrived today and WOW! What in the world of swimsuit magic is this wizardry? This is, without a doubt, the BEST one piece I have EVER worn!!
It’s been a long time since I’ve felt confident (dare I say sexy, even 😉) in swimmers, but this has it in spades!
Thankyou Thankyou Thankyou Lyndi, Les, and the entire Fearless team for creating swimsuit dreams and restoring my summer energy ❤️
Much love,
Cate xx

Honestly the best swimsuit I’ve bought in years! I’m a 16G and I could fit into the suit comfortably- it’s so versatile. As soon as I’m cashed up I will be buying more Fearless in a heartbeat 💗
Stunning, tight, supportive. I love it! However, my boobs are just too big for this beauty. I can’t wait for you to bring out a swimsuit with underwire and for bigger boobs!! However, if my boobs were smaller I would wear this 24/7!!
Just beautiful, feminine, supportive but comfortably so. The fabric feels amazing, with a matt finish so you can wear with a skirt or shorts around the street or out to dinner as a body suit. The adjustable straps make it really easy to change the coverage. Absolutely love!
As a pear shape with a long body, I have spent decades wearing ill fitting bikinis and covering up in shirts, rashies and board shorts.
I ordered the All Day suit in long torso, in a size to fit my butt, and it’s honestly Amazing!
The quality’s fantastic, the butt coverage is perfect, and the cross over back and adjustable bust means it fits my smaller top too! No riding up. No cutting off circulation. No accidental exposure.
For long bodied woman with junk in the trunk but not much up front this works beautifully.
Thank you, thank you, thank you!

Absolutely stunning swimsuit. Quality is totally amazing. The straps are strong and offer amazing support. This is the most beautiful swimsuit I’ve ever owned. Certainly won’t be my last. Beautiful work Fearless Team.
I couldn’t wait to get away to wear my new All Day one piece in teal to the beach. It felt so good being held in in all the right places as I was walking in and out of the water . I actually enjoyed the fact people were looking as I felt absolutely fabulous in them! I felt that good I am going to purchase the two piece All Day as well.
It's going to be a good summer in these. Absolutely LOVE the.
I LOVE these and can't wait for the weather to warm up enough to take them out for a swim! I couldn't go past the teal and just love everything you guys are doing!
I couldn’t wait to get on holidays so I could wear my Teal All Day swimsuit. I felt fabulous in it and walking in and out of the water I felt so confident that I was being held firm in all the right places.
AMAZING, INCREDIBLE, FABULOUS! This one piece is the best thing that has ever happened to me. Coming out of postpartum I needed a swimsuit that made me feel cute and this does the trick. The fabric and cut are gorgeous, the compression is lovely and not too tight. I've been wearing as a bodysuit and I could live in it! Also, it's so breastfeeding friendly and doesn't cut into your bum. If I could give this more than 5 stars I would.
Thank you, Thank you, Thank you! 🤩
I’m pear shaped with a long torso, I have spent decades wearing ill fitting bikinis and then covering up in shirts, rashies and board shorts.
I ordered the All Day suit in long torso, measured it to fit my butt and literally held my breath while trying it on.
It’s Amazing!

I’ll probably get another to try the magic sizing, but I wanted you to know that this also works for us long bodied woman with junk in the trunk but not much up front.
I’m so grateful you saw the need, listened to the people, and took the risk. Never ever doubt the difference you are making. ❤️
