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! We recommend measuring this part in Inches and converting it to CMs.
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!
| 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.

Join 75,000+ women who found the strapless bra that actually stays put. MagicLift™ security + CloudSoft™ comfort = finally, proof.
This bra features an unpadded, entirely wireless compression-style fit designed to hug your rib cage securely for a reliable strapless hold. The band provides the main support, so choosing the correct band and cup combination is essential for comfort and stability.
CRITICAL FIT & SIZE GUIDANCE FOR UK BUYERS:
- Measure Before Ordering: Measure your underbust and bust and compare both measurements with the size chart. Your measurements should guide your size selection rather than relying only on your usual bra size.
- Get the Band Right: The band should feel secure and stay in place without digging, pinching, or feeling excessively tight. If the band is too loose, it may not provide the support expected from a strapless bra.
- Get the Cup Right: The cups should comfortably contain your bust without spillage, bulging, excessive pressure, or noticeable gaping. If your bust measurement is near the upper end of the recommended range, make sure the selected cup provides enough coverage.
- Between Two Sizes? Choose the size that gives you enough cup coverage while maintaining a secure band fit. If you prefer more comfort or have a fuller bust, choose the larger option rather than forcing yourself into a smaller size.
- Fuller Bust: If you have a fuller bust, prioritize adequate cup coverage and comfort rather than automatically sizing up the entire bra. A larger band can reduce the secure hold needed for a strapless style
- What to Expect: This is a wireless compression bandeau, so a firm, secure feel is expected. However, it should not feel painfully tight, restrict movement, or cause excessive pressure. The bra should remain comfortably secure while providing the level of support described for this style.
Still unsure about your band or cup size? Contact our Customer Support team before ordering we're happy to help you find the right size.

Fabric & Care
Fabric & Care
Fabric & Technical Build
- Body Composition: 84% Stretch Performance Nylon, 16% Elastane Comfort Matrix.
- Cup Architecture: Entirely wireless, unpadded, and unlined flat-knit compression panels (no foam cups or removable pad inserts).
- Hardware Core: Front-locking variable adjustment polymer snap buckle combined with multi-hook inner rear fasteners.
- Trim Detailing: Integrated flat-stitched lace perimeter accent border.
Intimate Apparel Care Instructions
To keep the delicate lace borders pristine and maintain the high-stretch band memory, follow these care tips:
- Hand Wash Recommended: Wash gently in cool water with a mild detergent to protect the soft knit fibers and prevent the lace trim from fraying.
- Secure Buckles Prior to Washing: Snap the front buckle shut before washing to avoid twisting or snagging the mesh fabric.
- Air Dry Only: Lay flat to dry away from direct heat. Never use bleach or high-heat tumble dryers, as extreme heat will degrade the elastane core and warp the front closure hardware.

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.
- This measurement is your BUST size.

We Get These Questions A Lot
Supportive answers for your most common bra dilemmas.
How can I make sure I order the correct size?
To find your best fit, we recommend measuring your underbust and bust and comparing your measurements with our size chart instead of relying on your usual bra size. If you need help choosing, our Customer Support team is happy to assist before you place your order.
Will this actually stay up? I've been burned by "strapless" bras that end up around my waist by noon.
We get it—you've tried the others. Here's the difference: most strapless bras use a narrow friction band (which is why they slip). Our MagicLift™ technology distributes support across your entire torso, so it physically locks in place—even when you're raising your arms or dancing. Customers report it "didn't budge" through 14-hour weddings. That's not luck—that's engineering designed to work with your body, not fight it.
How does it stay secure without leaving painful red marks or feeling like a vice grip?
That's the problem we solved. Traditional bras use compression (squeezing) to stay put, which causes pain. MagicLift™ uses surface area distribution instead—spreading support across a wider band means less pressure per square inch. You get security without the squeeze. Pair that with CloudSoft™ fabric, and you get a bra that stays put AND feels soft all day. No trade-offs. No red trenches.
Can I actually wear this with backless, strapless, and off-shoulder styles? Like, will it really work?
Absolutely—that's what it's designed for. The strapless mode locks in place under any backless or strapless outfit, and the convertible straps give you halter or classic options for off-shoulder styles. Our customers have worn it to black-tie galas, weddings, and date nights—dancing all night without adjusting once. Finally wear what you want, not what your bra dictates.
Is it really comfortable enough to wear all day, or is this another "looks good but feels terrible" situation?
This is kind of our whole thing. CloudSoft™ fabric feels like a second skin—breathable, soft, and no digging. No underwire stabbing your ribs. No "counting down the minutes until I can take this off" energy. Customers say they "literally forgot they were wearing it" through 12-hour workdays. That's the standard we built to—all-day wearability, not just survive-the-event tolerance.
What makes Magic Bra different from the five other strapless bras collecting dust in my drawer?
Fair question. Here's what's different: we engineered MagicLift™ and CloudSoft™ specifically to solve the strapless paradox (stays up without painful squeezing). We don't ask you to "break it in for 30 wears"—it works from day one. And we have 75,000+ verified customers who've said this is the first strapless bra that actually delivered on its promise. Read the reviews—they're real women, real results.
What if I'm between sizes or not sure which size to order?
Check "The Fit" section on this page—it's tailored specifically for this bra's sizing. We offer expanded sizing to ensure a great fit. Still unsure? Message us—we're real humans who'll help you figure it out. And if the fit isn't perfect when it arrives, you've got 30 days to exchange sizes or return it. No hassle, no pressure.
What's your return policy? I've had too many bad online bra experiences.
Totally fair—we'd be skeptical too. Here's the deal: try it at home for 30 days. Wear it. Wash it. Dance in it. If it's not the most secure, comfortable strapless bra you've ever owned, reach out and we'll process your return or exchange—no drama, no interrogation, no "but did you follow the care instructions" guilt trip. We just want you to find a bra that actually works.
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 praised this strapless wireless bra for exceptional support and all-day comfort. The front buckle design "gives a little lift without needing underwire," while silicone grip keeps it secure without slipping. Shoppers loved the convertible straps and soft fabric that works under sheer clothing. Sizing runs small; customers recommend sizing up per chart.

The shallow cup design holds everything firmly in place! It brings my chest together, creating a compact look that makes me appear slimmer. It didnt shift at all throughout the day, and my cleavage stayed exactly the same from morning to night. I loved it so much I bought another one!
This bra doesnt shift at all, and since the fabric has a soft, texture, it works well under sheer tops too! Im on the slimmer side, and even the medium size felt a little tight. If you prioritize comfort. I bought the beige and wite color. Yey! Thanks Magic Bra
This bra is comfortable and provides a nice hold. Many strapless bras tend to squeeze too much, but this one is wide enough to avoid that problem. The fabric looks stylish enough that you can wear it under sheer clothing.
The value for the price is unbeatable! I usually wear a 5XL, and Ive struggled to find a bra that provides proper support without slipping, until now. This is the first product that truly satisfies me! Its sturdy, supportive, and has a cute design. Highly recommend!
My daughter loves this strapless bra says it is comfortable and doesnt fill like its slipping (like others do). We followed the size chart (very important!) and it fits her great. Shes normally a L, but had to get an XL as the size chart recommended.
My mom loves this bra so much that she had me buy another one! It keeps her cool, feels secure, and does the job wonderfully. It provides great support for around a DD cup.
I love the way it looks and feels! The fabric is lovely and provides a flattering fit.
This bra is comfortable and easy to secure with the front closure. While it can be worn strapless, it includes convertible straps for extra support. I wore it all day and it stayed in place without constant adjustments.
I’m always a little skeptical with strapless bras because they either slide down, feel uncomfortable, or just don’t give any support… but I needed something for the cruise so I decided to try this one. The strap underneath the chest is such a brilliant placement! The bra stays in place. The silicone grip really does its job, and I’m not constantly adjusting it all day, which is usually my biggest issue with strapless bras. It feels secure without feeling tight or annoying. The front hook design is really the beat—it gives a little lift without needing underwire, and you can adjust it depending on how much support you want. It still feels comfortable and not bulky, which I appreciate.
I wore this under a bridesmaid dress this weekend and it was so comfortable & supportive Nothing rubbed me uncomfortable at all and it stayed up the whole time.
WE LADIES KNOW HOW HARD IT IS TO BUY A STRAPLESS BRA IN PERSON SO IMAGINE ONLINE. HOURS OF LOOKING AND I FOUND THE PERFECT BRA. NO SLIPPING NO CONSTANT ADJUSTMENTS. I'M VERY HAPPY. I HOPE THIS HELPS.
Adding more stars ☆☆☆☆☆☆☆☆☆☆☆ fast shipping. Package was great.
With summer approaching, I bought this as a layering piece under cropped tops. I was worried about the fit, but its lightweight, comfortable, and has great non-slip support. It can be worn with or without straps, making it super versatile. I might get another one in a different color!
Very comfortable, doesnt slip, and works well for different outfits.
No need to worry about straps falling off, even without them, this bra stays in place. It also remains invisible under light-colored clothing, which is a huge plus.
I bought this to wear with a backless dress. I followed the size chart, and it was a great success! Its designed to keep everything smooth without creating cleavage, and it doesnt show through clothing. The soft material, good fit, and great price make it a winner.
I usually buy bras like this in stores, so I wasnt sure what to expect. This was my first time using a front buckle, and I was surprised by how secure it feels. I wore it around the house before heading out, and it didnt move at all. The strap is a nice option, but honestly, I didnt even need it.
This is a great strapless bra. The band sits comfortably below the bust, and the removable padding provides great coverage. I even wear it while doing yard work, and it stays in place better than expected!
Some things you dont realize until you actually wear it, but the underband is well-adjusted and super comfortable! It also comes with a strap in case you ever want extra support.
It fits well even on bless chest like me and stays securely in place, even when jumping. The anti-slip design provides excellent support, though it can be a bit tricky to put on. Overall, its a great option for those with larger breasts.
Soft, easy to wear, and stays in place all day! Although the delivery was bit late but it was perfect fit for me
No matter what kind of bra I wear, my shoulders get stiff due to shoulder straps, and Ive been looking for strapless bras and bought various things, but this one is amazing! The fabric is soft, it fits perfectly.
Like many other reviewers mentioned, I went up a size, and it ended up fitting perfectly! (Or maybe I just gained weight... lol.) If you overeat, it might feel a bit tight, but it doesnt slip, and the shape stays smooth under clothes. I love it! Time to hit the gym!
I was worried because its a big bust, but its perfect for my size.
I love that it stays in place even without straps! Its perfect for outfits that show off the shoulders and is super convenient to have.
I use it to go for a run. It gives excellent support and is very practical. Really a well-made and useful garment as well as of excellent quality!
Very good, good support and easy to put on. Removable shoulder strap
Typically, most bras flip from. The top, well this one stays!! It feels good all around the body and it never slides down.
My daughter was so happy, it fits her perfectly
