Bra Sizing Guide
Getting the right fit doesn't need to be hard, let us help you make sure you get the right fit.
Band Size
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!
Cup 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!

Key features
The fit
Finally, the strapless bra that stays up without torturing you.
CloudSoft™ Seamless Confidence
Silky-smooth, seamless fabric that feels amazing against your skin. Instant comfort, all-day softness from the moment you clasp it.
Corset-Style Posture Support
A firm, shaping back panel designed to hug your ribcage for real lift and posture support. You'll feel held and supported all day long.
Strapless That Stays Up
Built to be worn securely and close to the body, which is why many customers get their best fit by choosing a slightly smaller band size.
Compression Push-Up Cups
Cups designed to compress and lift for natural-looking cleavage and shaping. Expect a close, molding fit that creates real lift and holds its shape all day.
Back-Smoothing Coverage
Wide, structured back that smooths bulges and gently supports your posture. The firm coverage gives you that seamless silhouette you'll love under any outfit.
Convertible Support Straps
Wear it strapless, halter, or cross-back. Since the support comes from the snug corset band, your straps become styling choices. Freedom to wear what you love.
Stays put all day. Leaves zero marks. Makes you forget it's there. This is the strapless bra you thought was a myth—and 75,000+ women finally found.
This corset-style posture bra runs large in the band, so ordering your usual bra size may feel loose and unsupportive. For the best lift and secure strapless hold, size down one band size first (for example, 36C → 34C).
The cups are designed to compress and push up for shaping; size up in the cup only if you prefer a more relaxed feel.
If you are between sizes, choose the smaller band for better support and cleavage.
For the best fit and comfort, our pre-shrunk fabric ensures your size stays consistent wash after wash.
Bra sizes can vary by style. For your best fit, please use our size chart before ordering.
Description
You're Not Imagining It—Strapless Bras Are Designed to Fail You
You know that pre-event dread when you realize your outfit needs a strapless bra? The hours spent hunting through your drawer, trying on five different options, all of them either slipping down within 20 minutes or digging so hard they leave angry red trenches that sting in the shower the next day. By the time you leave the house, you're already planning bathroom breaks to yank it back up, arms glued to your sides, counting the minutes until you can rip the thing off.
Here's why: every other strapless bra uses rigid grip technology—stiff underwires, aggressive boning, vice-grip bands—because that's the only way they know how to create security. The problem? Those rigid components create pressure points that dig into your ribs, squeeze flesh out around the band, and leave you with welts and bruises. The "solution" becomes its own torture device. You're stuck choosing: public humiliation when it falls to your waist, or physical pain for 8+ hours.
Our FlexGrip™ multi-band system does what rigid bras can't: distributes anchor pressure across three contact points instead of crushing one. The flexible construction grips without gouging. It's engineered to handle the physics of a DD+ or 36H bust—which means if it locks in place on them, it absolutely will on you. No slipping. No digging. No choosing between security and survival.
Picture this: You put on that backless dress you bought two years ago but never wore. You dance, you hug, you raise your arms—and the bra doesn't move. Not one millimeter. And when you finally take it off at midnight? Your skin is smooth. No red marks. No welts. No evidence you tortured yourself for beauty. Customers say things like "forgot I was wearing it for 14 hours" and "danced all night, never adjusted once."
Over 75,000 women have stopped settling for the "slips or hurts" paradox. This is the strapless bra that works like it's supposed to.

Size guide
Getting the right bra fit is easy! Just follow these two simple steps.
Step 1: Find Your Underbust Measurement
Ask a friend to help measure, or stand in front of a mirror.
Relax your arms by your sides.
Wrap a measuring tape snugly around your ribcage, just below your bust.
Make sure the tape is straight and level all the way around.
It's best to do this without a bra, or with a strapless, unpadded bra (make sure the tape isn't measuring over the bra itself).
This measurement is your UNDERBUST size.
Step 2: Find Your Bust Measurement
Put on a strapless, unpadded bra.
Wrap the measuring tape around the fullest part of your bust (usually over your nipples).
Hold the tape firm but not too tight, making sure it's straight across your back and parallel to the floor.

We Get These Questions A Lot
Supportive answers for your most common bra dilemmas.
Will the bra actually stay up, or will I be yanking it back up by hour two?
Absolutely, this bra will stay up instead of sliding down thanks to our FlexGrip™ multi-band system. This corset-style construction distributes anchor pressure instead of crushing one spot on your ribcage. For the best "forget it's there" security, size down one band size so it fits close instead of loose.
Will this dig into my ribs or leave those angry red marks that sting in the shower?
Short answer: no gouging, no welts, no waking up with bruises you have to explain. This bra is designed to feel held and supported, not squeezed or crushed. The CloudSoft™ fabric adds invisible, second-skin softness against your body. You get the right support without the torture.
How is this different from every other strapless bra that's disappointed me?
We hear this constantly, and we understand. That’s why we designed the Strapless Push Up Posture Bra with a corset-style structure that wraps and supports your ribcage. Unlike most strapless bras out there, this one actually stays put and lifts. It will feel more secure and structured than a soft everyday bra, and that's exactly what makes it work.
And if it turns out not to be the right fit for you, we offer a 30-day return policy on unworn items so you can try it with confidence.
Why doesn't it feel like my regular everyday bra?
Because it's not supposed to. This is a shaping and posture bra designed for lift, structure, and strapless security, so it feels firmer and more supportive than your go-to wireless lounger. The CloudSoft™ fabric provides posture support while the FlexGrip™ band keeps everything locked in place.
My cups feel tight, or I'm seeing gaps. What do I do?
Both are fixable. If you want a bit more breathing room, size up one cup. If you're seeing gaps at the top of the cup, it usually means the band is too loose and your body weight is pulling everything down. A smaller band brings the cups closer to your body for a smoother, more lifted look.
What if it slides down on me?
That's a band fit issue, not a bra failure. The FlexGrip™ band is what gives this bra its "magic." It needs to grip your ribcage to stay put. If it's sliding, your band is too loose. Size down one band size (keep the cup the same), and the difference will be immediate. If you can fit more than one finger under the band, it's too big.
Is this a good everyday bra?
Depends on what you need. This bra is perfect for days when you want to feel lifted, smoothed, and confident especially under strapless, off-shoulder, or fitted outfits. The CloudSoft™ seamless construction makes it invisible under clingy fabrics, and the convertible styling means you can wear it with or without straps depending on your outfit.
It's built for shaping and structure, so if you're looking for ultra-soft vibes for lounging at home, this one may feel more structured than your usual.
Because Magic Bra isn’t a promise — it’s proof. 75,000+ women wear it, love it, and say it’s the best switch they’ve made.

Customers say
This Victoria Secret bra provides a comfortable, flattering fit with a noticeable lift, even for those without large breasts. The posture-enhancing design helps reduce hunching. While it requires putting on over the head, the smooth, seamless construction and excellent shaping make it a great choice for all-day comfort. Some may wish for an open back, but overall, it delivers on comfort, support, and style.
Bit large from what i ordered, but guess what? its perfect!

If you’re between sizes, definitely go with the smaller option. It’s got a naturally roomy fit anyway.

Not what I wanted
I saw an ad for a strapless bra and ordered 2. When they arrived, they had straps. Not sure why a strapless bra was advertised if they send one with straps. As bras with straps, I'm sure they're OK. Don't need them however.

I usually wear a Large, but the Medium fits me exactly how I wanted. The material is super high quality, just keep the sizing in mind!

I was worried the smaller size would be too tight, but it’s actually just right. It still has that relaxed vibe without looking baggy.

It runs pretty large, so I took the advice to size down and I’m so glad I did. It’s my new favorite piece.
