Arriving mid October 2026.

The bikini top that brings the support without sacrificing the sexy. Structured underwire lifts and holds, while thick-but-feminine straps and an adjustable under-bust let you decide the fit. Thin foam cups give you a smooth, natural shape with no show-through, no bulky padding and no awkward folding. Finished with a cutaway centre front and open neckline for a little more skin and a lot more confidence.

Because when your bikini actually holds you where it should, you can stop thinking about it and start feeling yourself.

• UNDERWIRE SUPPORT - structured underwire delivers genuine lift and hold, designed for busts who need more than a triangle top.
• CUP - suits a range of cup sizes from C-D. 
• ADJUSTABLE FIT - customisable under-bust band lets you control compression and fit and adjustable straps
• FOAM CUPS - thin foam lining for modesty and a natural, rounded shape with no show-through or stiff padding
• HARDWARE - brushed gold Fearless hardware for a polished finish
• FABRIC - chlorine-resistant Luxe Crinkle (chlorine resistance 4/5)
• SIZE RANGE - XS-3X (Australian sizes 8-20)

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

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

Then go have a nap - because laundry is the worst.

FAQs

Does this top have an underwire?
Yes. The Balconette Top is built around structured underwire that delivers genuine lift and hold - designed for C-D cup women who need real support, not just the illusion of it.

Does it suit a fuller bust?
It's specifically designed for C-D cups. The underwire structure, adjustable under-bust band and foam cups work together to give you lift, shape and hold - not just coverage.

Does it have padding?
Thin foam cups only - enough for modesty and a natural rounded shape, but nothing stiff, bulky or prone to floating. No show-through, no padding that folds.

Does it run true to size?
Yes. Choose your usual size based on our size guide.

What's the coverage like?
The open neckline and cutaway centre-front detail keep it looking chic rather than sporty. Coverage is moderate - it's designed to feel secure and confident, not revealing.

What's the fabric like?
Luxe Crinkle with a 4/5 chlorine resistance rating and brushed gold Fearless hardware. It's a fabric that holds its shape and looks as good at the end of the day as it did at the start.

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

We Found a Gap in the Market

Most bikini tops ask you to choose between support and style. The Underwire Balconette Top doesn't. Built with genuine underwire structure, thick-but-feminine straps, and an adjustable under-bust band, it delivers the lift and hold that triangle tops simply can't - without sacrificing the look.

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.
