Getting the right fit doesn't need to be hard, let us help you make sure you get the right fit.
Okay — breathe in, then out, and hold. Wrap a tape measure around your chest at band level and take a look.
Odd number? Add 1. Even number? Add 2.
For example — if you measured 33” and add 1, you get 34”. This is your band size!
Breathe in again, then out, and hold.
1. Wrap a tape measure around the fullest part of your bust and take note.
2. Round to the nearest whole number. This is your bust size!
3. Subtract your band size from your bust size and voila! This determines your cup size.
For example — if your bust measured to 36, you would subtract 34 from 36 to get 2!
| INCHES | 1 | 2 | 3 | 4 | 5 | 6 |
| CUP SIZE | A | B | C | D | DD | DDD |
Put your band size and cup size together and now you have your bra size!
Our example comes out to be a 34B.

Support that doesn't squeeze. Lift that doesn't lie. Coverage that disappears. Thousands of women have already stopped fighting their strapless bras and started forgetting they're wearing one.
Tired of the strapless bra sizing guessing game? This one is straightforward.
Order your usual bra size. The anti-slip band and multi-row side hooks are engineered to deliver secure, no-slip wear at your true size, so you don't need to size down.
Between sizes? Go a size down for a snugger grip and maximum security. Stay at your usual size for a softer, more breathable feel.
Check our size chart to confirm your underbust measurement. And if the fit is not right? We offer hassle-free returns on any of your orders. We've got you.
You know the impossible choice: rigid, wire-heavy bras that lock you in place but leave red marks in your ribs by hour two. Or soft, "comfortable" styles that slip down the second you raise your arms.
Here's what's been holding you back: traditional strapless bras rely on squeezing or surrendering, neither of which solves the real problem. Our Anti-Slip Grip Band™ uses surface friction to hold your ribcage without crushing it. Multi-row side hooks let you adjust your exact tension. And pre-shaped molded cups deliver real, rounded lift that’s flattering on any body.
Security and comfort aren't opposites. You just needed a bra engineered to deliver both, from the first hook to the last hour of your night.
Fabrics:
80% Polyamide, 20% Spandex. Engineered for grip, comfort, and shape retention.
What This Means for You:
The polyamide blend gives the band its signature anti-slip grip, while the spandex delivers four-way stretch that moves with your body. The combination keeps the bra hugging your ribcage without squeezing, breathable enough for hours of wear, and structured enough to hold its sculpted shape.
Care Instructions:
Hand wash cold with mild detergent. Lay flat to dry. Do not bleach, tumble dry, or iron.
Pro tip: washing inside a lingerie bag protects the molded cups and extends the life of your bra.
Why It Matters:
A strapless bra is only as good as its grip and its shape. Quality care keeps both intact, so the bra you love at week one still works months later. Built to last, not to disappoint after three wears.

Supportive answers for your most common bra dilemmas.
It stays up. Our Anti-Slip Grip Band™ grips your ribcage with surface friction instead of relying on a tight squeeze, and the multi-row side hooks let you lock in the right band tension for your body. That said, fit is everything with strapless bras. Get the right size and the band does the work, so you can keep your hands off it.
This bra is engineered to grip, not crush. The anti-slip band uses friction to stay put, which means it does not need to be vice-tight to hold you up. The seamless edges sit flat against your skin instead of digging in, and the soft polyamide-spandex blend feels closer to second skin than a torture device.
Pre-shaped molded cups are designed to deliver natural, rounded lift without the uniboob shape or pointy weirdness that ruins most strapless push-ups. Keep the pads in for fuller cleavage, take them out for a softer, more natural silhouette. Either way, you get real shape, not flat and not exaggerated.
No. Seamless molded edges and a smooth surface are designed to disappear under fitted tops, slip dresses, and bodycon styles. You won’t have to worry about visible lines, lumps, or obvious bra outlines. This is the bra for the outfits where every other bra would have shown.
The molded cups and multi-row side hooks are designed to support a range of bust sizes, and the anti-slip band gives you mechanical grip that does not depend on bust size to work. Larger busts may want to size down for a snugger band feel. Check the size chart and order in your true size, then adjust from there.
Size down for a snugger grip and maximum security. Stay at your usual size for a softer, more breathable feel. Both work, it just depends on whether you prioritize lockdown hold or all-day comfort.
We get it, online bra shopping can feel like a gamble. That's why we offer hassle-free returns if the fit isn't right. We want you to love it from the first hook, but if it's not right, we'll make it right.

Also spot on for a larger bust—love it!
Bloody comfy.
I just had to write this. For years, I’ve been buying strapless bras only to be let down every time. They either wouldn't hold the girls up or I’d be spilling out the second I moved. I eventually just gave up and stopped wearing tube tops or anything strapless altogether. I heard about these and figured I’d give it one last crack. As soon as it arrived, I chucked it on and did jumping jacks—I was certain I’d be sending it straight back. But oh my god, it didn’t budge! It didn’t slide down, I didn't pop out, and the girls were actually supported.
Ripper bra
It’s a spot on fit, true to size.
It's a nice light nude shade and the fabric's decent.
I needed a strapless bra for a few tops I’ve got, so I thought I’d give this one a burl. I went a size up from what I thought I’d need and I’m glad I did; it’s a tiny bit big on me, but at least it doesn't smash my chest flat. The bra is soft and comfy, and the colour is spot on for the shirt I bought it for.
I’ve been on the hunt for a proper bra to wear with a one shoulder dress for my daughter's wedding. This one is super soft and gives just the right amount of support.
This strapless bra is a winner. It's got really good hold, and I never had to fuss with it once. Highly recommend.
Essential strapless bra everyone needs! Doesn't slip or slide, and it's true to size. Great quality—would highly recommend.
Fits like a glove and heaps comfy.
Fits a treat even without the straps, and it’s heaps comfy.
I've never actually written a review before, but I love this bra! It’s nice and thick, so it holds everything in place properly.
The material is soft and looks pretty seamless under tight tees and singlets. Seems like good quality gear, but only time will tell after it’s been through the wash a few more times.
Perfect for a larger bust!! It holds everything together well and those invisible straps are actually comfy. Shipping was super quick, too :) definitely recommend!
Shockingly good fit. Offers enough support I'm a 16DD. Worked perfectly for what I needed without giving me that dreaded uni boob look. The bands can get a little bit uncomfortable after long hours of wear, though, since they're designed to be nonslip.
