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
Power mesh: 72% nylon, 28% elastane
Sustainability isn’t just about recycled materials - it’s about choosing high quality pieces that last season after season. With the right care, your Fearless swim will go the distance.
Care Tips:- Rinse in fresh water after every wear, especially after pools or spas
- Cold hand wash or gentle cold cycle
- Avoid tumble drying, bleaching, soaking or ironing
- Dry in the shade
Then treat yourself to a nap - because laundry is the worst.

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?
Absolutely. It's designed to support A-F cup busts with wire-free built-in bust support and adjustable bust sliders so you can customise your lift.
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 Our Fit Is Different
We surveyed 15,000 women before launching a single product and we're still listening.
Most brands start at a size 6. We start at size 12 - because that's where our customer actually is. We test every garment on two base sizes simultaneously: a 10/12 (C-Cup) and a 14/16 (E-Cup), across real women before a single piece goes to production.
Our fit model is 35 years old and 165cm - not a tall runway model. We then proof every garment on women in their 20s through to their 60s, across XS-3X, because ten size-12 women look completely different from each other.
Customer perception of fit always trumps the data. When our fabric ran small, we changed our sizing.
Every model's size and measurements are on site. Toggle between model sizes to see the garment on a body closer to yours. Real women, real sizes, on every product page.
Sizes XS-3X. Built for the body you actually have.
