FAQs
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.

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.

Customers praised this confidence-boosting bikini top for its "quality material," compression, and supportive fit. Many said it's "the comfiest bikini" they've worn. The adjustable toggles allow different looks. Some concerns: the band width could be wider for coverage, and clasps "come undone easily."
- This is the comfiest bikini I've ever worn. The fabric is of such high quality.
- I never thought I'd have the confidence to try a bikini, but I trusted this brand.
- Strong, supportive, compressive fabric but totally comfortable enough to stay in all day!
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 ;)
AMAZING
I love my black all day Bikini and bottoms. I feel very well supported in the right kinda way❤️
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.
G cup and it has fitted quite well. Very comfortable
Quality material and despite me having some trouble working out where to put my head and my arms, it’s an amazing fit
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 post partum body, won't be hiding in boardies and tshirt this summer! Initially purchased the wrong size, exchange was very quick and easy, thank you!!
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.
By far the best swimmers I have ever worn. The pants feel so firm and hug the right bits. Can't wait to show it off at the beach!
I'm not usually a bikini gal but this is one I can get on board with. Amazing quality and love the compression. Well done guys!
I’ve just received my exchange (after getting myself the wrong size first time round) and let me tell you…this bikini is amazing! Love the colour. Love the fit! And the exchange process was so easy and stress free! Thank you Fearless team! Can’t wait to wear this bikini all summer long!
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.
