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.

Wore it all day and evening at a wedding was really comfortable and didn't slip down.
Was perfect for my large bust!! It holds well and the invisible straps are comfy! I got it shipped quickly :) def recommend!
This bra is amazing! Truly stays in place with zero tugging!!!!! Also very supportive. I have purchased several!
I had to write this. For years I bought strapless bras only to be disappointed. They wouldn't hold my girls up or they would spill out when I moved a certain way. I stopped buying them. I stopped wearing tube tops and strapless anything. I heard about these and thought I'd try one more time. As soon as I got this I put it on and did jumping jacks. I just knew I was gonna have to return it. OMG, It didn't move! It didn't fall down. I didn't pop out of it. The girls were supported.
This strapless bra is surprisingly comfortable and stays in place really well throughout the day. The material feels soft and smooth, making it perfect under tops where you don't want lines showing. I also like that it gives a nice shape without needing wires. The only downside is that it may need adjusting after long wear, but overall it's a great everyday option for the price.
Perfect bra! The material is smooth and doesn't feel cheap and doesn't slip down at all stays in place.
Shockingly good fit. Offers enough support- 38DD. Worked perfectly for what I needed without making me look like I have a uni-boob. The bands can get a little uncomfortable since it's non-slip, after long long hours of wear.
This strapless bra is great. Has really good hold. I never had to fuss with it. I highly recommend
Very comfortable. Highly recoimmended!
Fits great. Good without the straps, Tried it on with the dress I got it for. Perfect!!
This was very comfortable
I needed a strapless bra for a few shirts I have so I thought I would give this one a try. I got a size bigger than what I thought I would need and glad I did, it is a little big on me, but it doesn't smash my chest flat. The bra is soft and comfortable. The color is perfect for the one shirt I have.
Very comfortable
I have been searching for appropriate bra to wear for one shoulder dress for my daughter's wedding. This is super soft and just enough support.
t fits very well even without straps and is comfortable.
Staple strapless bra everyone needs! Doesn't slip or slide fits true to size Great quality would highly recommend
