Details

The Underwire Balconette Bikini Top was built for women who've given up on bikinis that don't actually hold you in place. Underwire structure, thick-but-feminine straps, an adjustable under-bust, and thin foam cups so no nipple shows through - and no padding that folds or floats. A cutaway centre-front detail and open neckline keep it looking chic and modern.

• UNDERWIRE SUPPORT - structured underwire delivers genuine lift and hold, built for busts who need more than a triangle top, larger bust friendly
• CUP SIZES - Suits a range of cup sizes from B-F. E-F cup sizes arriving September
• ADJUSTABLE FIT - customisable under-bust band lets you control compression and fit, not just size
• FOAM CUPS - thin foam lining for modesty and a natural, rounded shape, no show-through, no 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 6-20)

Pairs beautifully with the Side Tie High Waisted Bottoms.

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

Sustainability isn’t just about recycled materials - it’s about choosing well made pieces that last season after season. With the right care, your Fearless swimwear will keep looking incredible for years.

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
  • Avoid tumble drying, bleaching, soaking or ironing
  • Dry in the shade

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.

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.

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.

Fabrication: LuxeCrinkle

Soft, textured, and incredibly forgiving. The crinkle construction naturally adapts to your shape - smoothing and supporting without ever feeling tight or restrictive. The texture also helps disguise areas you may feel self-conscious about, while creating a modern, elevated look.

Texture: Sculpting crinkle
Support: Flexible, comfortable hold
Chlorine resistance: 4/5
Best for: Relaxed feel, disguising texture
