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.

Confidently wear your favorite dress or top, with support that stays put all day.
Perfect for every strapless dress, off-shoulder top, or special occasion when you want to feel secure, free, and effortlessly beautiful.
A secure strapless fit starts with the right band and cup combination.This strapless bra is designed to stay securely in place with a firm, supportive band. For the best fit, measure both your underbust and fullest bust before ordering.
- Measure before ordering: Use your measurements and the size chart rather than relying only on your usual bra size.
- Band fit: The band should feel snug and secure without being painfully tight. If it feels loose or slips, try a smaller band. If it feels too tight, try the next band size up.
- Cup fit: If the band fits but the cups feel tight, cause spillage, or do not fully contain your bust, choose more cup room. If the cups gap, try a smaller cup.
- Between sizes: Choose the size that gives you enough band support and cup coverage. Fuller-bust customers should pay extra attention to cup room.
- Fit feels different from a previous order? If the same labelled size feels noticeably tighter, looser, or different between colours or orders, please contact Customer Support before exchanging for another size so we can help check the fit.
- What the fit should feel like: The band should stay firmly in place while the cups fully contain your bust without excessive spilling, gapping, or pressure.
Still unsure? Contact our Customer Support team with your usual bra size, underbust measurement, and fullest bust measurement, and we’ll help guide you to the best fit.

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.
Does this bra run true to size?
Fit can vary depending on your band and cup combination, so we recommend measuring your underbust and fullest bust before ordering instead of relying only on your usual bra size. Use our Size Guide to find your closest match.
What if the band feels loose or the bra slips down?
A strapless bra needs a firm, secure band to stay in place. If the band feels loose or moves when you raise your arms, try a smaller band size while adjusting the cup size separately if needed.
What if the cups feel tight or I have spillage?
If the band feels secure but the cups are too tight or your bust spills over the edges, keep the same band size and try one cup size larger.
What if there is space or gapping at the top of the cups?
Gapping can mean the cup is too large or that the cup shape is not the best match for your bust. Try a smaller cup size while keeping your band size the same.
Can I just order my normal bra size?
We recommend measuring first because bra sizing can vary between styles. Your underbust measurement helps determine your band, while your fullest bust measurement helps determine your cup.
What if my bra fits differently from another colour in the same size?
If two bras in the same labelled size fit noticeably differently, please contact Customer Support before wearing or returning the item so we can help check the sizing.
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 bra as "the best" they've found, with exceptional support for larger cup sizes. "Stays in place" without constant adjusting and provides an "hourglass shape." Sizing guidance is critical: customers recommend going down a band size if between sizes, as the grippy lining needs to be snug to work. Proper measuring is essential for optimal fit.

No More Bra Worries! The Magic Convertible Non-Slip Strapless Bra is perfect for low-back dresses. The clear straps are barely noticeable, and I felt confident and comfortable all night at the gala event. Thank you!
Great for All Sizes! As a plus-size woman, finding a reliable strapless bra was challenging. This bra not only stayed in place but also gave me the support I needed. I'm thrilled with my purchase
So Comfortable! I wore this bra during a long flight, and it was a lifesaver! No digging or discomfort, and it stayed put even during turbulence. This is the only strapless bra I'll ever need.
Versatile and Practical! The Magic Convertible Non-Slip Strapless Bra is fantastic. I love how it can be worn in multiple ways, making it suitable for various dresses and tops. The quality is top-notch too!
No More Falling Straps! This bra is a game-changer for off-shoulder outfits. The non-slip feature is incredible - no more embarrassing moments of readjusting my bra. It stays put all day!
Support without Compromise! I'm a fitness enthusiast, and I've been searching for a strapless bra that provides support during workouts.
i was between two bands n went with the smaller one after readin the fit guide. right call. the grippy lining only works if the band is actually against you, theres nothin else keepin it there
measured properly this time instead of just guessin my usual size n it made such a difference 😌 band feels secure, cups sit nice, n it actually stays put
honestly wasnt sure which size to get cos the fit felt diffrent from another bra ive got. messaged them with my measurements n they helped me work out the better option. glad i asked rather than just guessin again
The best strapless bra I have ever found in my life. First one I have tried on that I am not spilling out of the sides or have to pull up every 10 seconds. Also looks great under tops. Will buy again and probably try their other bras as well. So comfortable and fits like a glove
This strapless bra is surprisingly supportive and comfortable. It stays in place well without constant adjusting, which is always my biggest concern with strapless styles.The cups are smooth and provide good shape without feeling stiff, and the band feels secure without digging in. I was able to wear it for several hours comfortably, and it worked well under dresses and tops without showing lines.Overall, this is a solid strapless bra if you’re looking for support, comfort, and a clean look under clothing.
This strapless bra is amazing. I am super excited to wear it with certain shirts and tank tops. So comfortable, I wish I had it for my wedding!
id check both when you try it on. my cups were ok but the band felt diffrent to what i expected. they helped me work out what actually needed changin instead of just sizin the whole thing up, which wouldve made it worse
This bra blew me away. I usually spend way more on bras thinking that’s the only way to get real support and comfort—but this one proves otherwise. It’s not only supportive for my DD cup size, but it’s also incredibly comfortable and minimizes just the right amount without digging into my sides. It sits naturally and feels so good on, I didn’t even use it as a strapless! I wore it under a blouse and it stayed in place all day. Total game changer. I’ll definitely be buying more!
mine felt a bit loose round the body at first, kept workin its way down on me. changed the band size n now it feels way more secure, specially strapless where theres nothin else holdin it up
Wow!! This bra is soft and a pretty color. I was not expecting that it has these cross stretchy straps in the back that not only hold up the bra but hold you in like a miracle! Suddenly I have an hourglass shape! This bra will not slip down and it’s pretty!
Genuinely one of THE best strapless bras for those of us who have a big chest. I took my measurements and received just what I expected they hold them in place they don’t smush them they are simply lovely. I bough them for summer but I use them regularly now as they are even comfier.
go one band down. my usual size just kept slidin down
band was fine, cups felt tight. kept the same band n went for more cup room. much better now 👍
Absolutely Love It! The Magic Convertible Non-Slip Strapless Bra is a game-changer. I wore it all day at my friend's wedding, and it stayed in place the entire time! No worries about adjusting it constantly. Highly recommend!
Best Bra Ever! This bra has made my life so much easier. I bought it for my prom night, and it worked wonders under my dress. Thanks to the Magic Convertible Non-Slip Strapless Bra, I danced all night without any discomfort!
A Must-Have for Every Woman! I've struggled with finding a good strapless bra until I found this gem. It provides excellent support and doesn't slip at all. I wear it regularly, and it's become my go-to bra for all my outfits.
Invisible and Seamless! I bought this bra for my wedding, and it was perfect. You couldn't see it at all under my dress, and I felt so confident throughout the entire day. Highly recommend it for brides-to-be
It's comfortable, versatile, and I can finally wear my favorite strapless dresses without constantly adjusting the bra. Love it!
