Fabric & Care

This swimsuit is made from an ultra matte, silky smooth fabric - so chic you can wear it as a bralette too. (Two looks, one purchase!)

Outer: 75% recycled nylon, 25% elastane
Lining: 86% polyester, 14% elastane

Sustainability isn’t just about recycled materials - it’s about investing in high quality pieces that last for seasons. With the right care, your Fearless swimwear will stay looking incredible wear after wear.

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

Does this top have an underwire?
No. This style is completely wire free with a built in under bust support. It's fully lined with no padding or foam inserts.
Does it suit a fuller bust?
Absolutely! This style is best suited for an A-F cup. If you have a fuller bust, you can cross the straps for maximum lift, no slips, no neck strain and zero adjusting - even on active beach days.
Does it run true to size?
Yes. Choose your usual size based on our size guide.
Is the coverage minimal?
Coverage is moderate with a flattering neckline - designed to feel confident, not revealing. There is a subtle peak of side boob but nothing too crazy!
Are colours true to photos?
Yes. Colours are photographed in natural light, but slight variation can occur depending on screen settings.
What's the fabric like?
Made from our UltraSmooth fabric with gunmetal hardware - this style also has a 4/5 chlorine resistance rating.
Does the All Day Bikini Top support large busts without underwire?
Yes - it's specifically designed to give A-F cups high bust support without underwire, using adjustable bust sliders and cross-back strap options for extra lift and security.
Does this bikini top have padding?
No - the All Day Top has no foam cups or padding. It relies on structure, lining and adjustable sliders to shape and support naturally.
What is the All Day Bikini Top best for?
It's ideal for women who want real bust support in a bikini without an underwire - perfect for beach days, pool days and holidays where you want confidence without discomfort.
Is the compression in this swimsuit comfortable?
Supportive doesn't have to mean uncomfortable. Fearless swimsuits are designed with sculpting compression that helps you feel held and supported - not squeezed or restricted. It's the kind of support that lets you feel secure in your swimsuit without counting down the minutes until you take it off.
Will this bikini top actually stay in place all day?
Yes - customers rave about the all-day wearability with zero constant adjusting. One reviewer specifically highlighted how good it felt not having to constantly adjust straps and pull out wedgies, and multiple reviewers call it the most comfortable bikini they’ve ever worn. The high-quality compressive fabric provides genuine support that keeps everything secure throughout the day, not just when you’re lying still.
Will this support larger cup sizes?
Yes - a G-cup customer confirms it fitted quite well and was very comfortable, proving this isn’t just another bikini that only works for smaller busts. The compressive fabric provides actual structure and hold, and multiple customers with different sizes praise the fit as flattering and supportive. The support doesn’t come at the cost of comfort either.
Is the fabric actually high quality or just marketing hype?
The fabric quality is the number one thing customers can’t stop talking about - mentioned positively in 5 out of 6 reviews with words like high quality, strong, and amazing. Reviewers describe it as strong, supportive, and compressive but totally comfortable enough to stay in all day. One customer who isn’t usually a bikini person said the quality won them over immediately.
I’m not usually a bikini person - will this actually be different?
One self-proclaimed not usually a bikini gal became a convert, saying this is one she can get on board with thanks to the quality and compression that makes it feel more like supportive activewear. The compressive, supportive fabric provides coverage and security that feels completely different from flimsy traditional bikinis, and the no-adjusting-needed fit helps even bikini-sceptics feel comfortable and confident.
How does the fit run - true to size?
The fit is consistently praised as flattering and true to size, including for a G-cup customer who found it fitted quite well. The compressive fabric moulds to your body rather than squeezing uncomfortably, providing structure while remaining wearable all day. One reviewer mentioned having a little trouble working out how to put it on initially, but called the final fit amazing - worth the brief learning curve.
What makes this worth the investment compared to cheaper bikinis?
Customers call it simply the best bikini you could buy, and here’s why: the all-day comfort is rare at any price point, the no-adjusting design saves real mental energy on every beach day, and the high-quality fabric suggests it will outlast multiple seasons of cheaper alternatives that lose shape and support after a few wears. One customer called it the comfiest bikini she’s ever worn - that’s a strong endorsement.
Is there anything I should know about the clasps?
One customer out of 6 reported finding the clasp mechanism on the straps and band came undone too easily and didn’t stay in the right place. This was an isolated concern not mentioned in other reviews, but it’s worth being aware of. If secure clasps are important to you, the cross-back strap option may give you more confidence and hold.
