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.

One Bra, Endless Confidence
Slip into support that works with you—not against you. From fast zips to breathable comfort and a flawless, smoothing fit, this bra is built to make every move feel better and every day feel easier. Wear it once, and you’ll wonder how you ever lived without it.
This bra fits true to size, so you can order your usual size with confidence. It’s designed to match standard measurements for a comfortable and reliable fit without guessing.
For the best fit and comfort, the wide support band and crossback straps keep support stable without needing to size down. We recommend choosing the larger size if you are between sizes. If our size chart suggests a Medium but you are close to a Large range, selecting a Large will provide a more relaxed feel while still offering the support you need.
Because fit can vary by style, especially with sports bras, please refer to our size chart before ordering for the most accurate result.

You know that impossible choice you've been forced to make with every sports bra you've ever bought?
Either you pick the compression style that supposedly "locks down support"—but makes you feel like you're being suffocated in a chest prison, leaves you gasping for air during cardio, and takes an actual wrestling match to peel off your sweaty body afterward. Or you go with something comfortable and breathable—only to discover during your first burpee that your boobs are bouncing so painfully you're literally hurting, turning every high-impact workout into a reminder that you made the wrong choice. Again.
Maybe you've even resorted to wearing two sports bras at once just to get decent support—which only makes the breathing and overheating problems twice as bad. Or maybe you've started avoiding running altogether because the pain just isn't worth it. And at the end of every single day, there's that moment—that "sweet, sweet release" when you finally get home, rip off your bra, and feel those painful red marks and bruises on your skin where the straps dug in all day long.
It's exhausting. And you shouldn't have to live like this.
Here's what the sports bra industry doesn't want you to know: the reason you've been stuck in this miserable trade-off isn't because support and comfort can't coexist. It's because traditional sports bra design relies on one of two fundamentally broken approaches. Compression bras try to flatten and squeeze everything into submission—which does reduce bounce, but only by restricting your breathing, limiting your movement, and leaving painful marks on your skin. Meanwhile, lighter "comfortable" styles simply don't have the structural engineering to control high-impact movement, leaving you literally bouncing and hurting when you need stability most.
That's the hidden problem—the Unique Mechanism Behind the Problem—that's kept you trapped between pain and more pain.
Our Front Zip Anti-Bounce Sports Bra solves this with an entirely different approach—one that gives you freedom from the torture. Instead of compression or flimsy fabric, we engineered a revolutionary support system that works with your body, not against it. The wide crossback straps distribute weight across your entire upper back and shoulders—completely eliminating the painful digging, bruising, and red marks of traditional straps while providing genuine lockdown support. The anti-vibration technology stops painful bounce at the source without squeezing the life out of you, so you get rock-solid stability without suffocation. And that front zip? It's not just convenient—it's your escape route from the daily wrestling match. Just pull, zip, done.
Imagine waking up and putting on a sports bra that actually feels good from the first second. Imagine running, jumping, doing burpees without once thinking about whether you're hurting or whether you can breathe. Imagine finishing your workout and removing your bra in two seconds flat—no struggle, no marks, no bruises—just freedom. That's not a fantasy. That's exactly what 17,000+ women are experiencing right now, every single day.
"I've been wearing two sports bras at once for YEARS because I needed support but couldn't breathe in just one. I thought that was just life. This is the first bra that gives me both. I actually forget I'm wearing it during my workout—and when I check myself out in the mirror afterward, I look amazing. Game changer." — Sarah M., Verified Buyer
You've been choosing between bad and worse for too long. You deserve freedom—from pain, from adjustment, from even thinking about your bra. It's time to experience what comfort + support actually feels like.

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.
Will Magic Bras actually support me — like, really support me?
Oh, 100%. Whether you’re a B cup or a G, Magic Bras are built to lift, shape, and hold you in — without squeezing or digging. They offer the kind of everyday support that moves with you, feels effortless, and still keeps everything right where it should be. You’ll feel the difference from the first wear.
Are they comfortable enough to wear all day?
Yep, that’s kind of our thing. We design every Magic Bra to feel like a second skin — breathable, soft, and smoothing in all the right places. No digging, no pinching, no “Can’t wait to take this off” energy. Just everyday confidence.
How do I know which style is right for me?
You don’t have to guess — that’s what we’re here for. From wireless comfort to sculpting support and everyday smoothing, we’ve got different styles to match what you need. Just check our fit guide or send us a quick message — we’ll help you find your favorite.
What makes it “magic” exactly?
It’s the way you feel when you wear it—and when you don’t have to think about it. Magic Bra lifts, smooths, and supports without the digging, tugging, or discomfort. You feel held, not restricted. That’s the kind of magic every woman deserves.
What if I’m between sizes or not sure what to get?
We’ve been there. Because sizing can vary between styles, we recommend checking The Fit section on each product page — it’s tailored for that specific bra. Our goal is to help you find a bra that feels like it was made just for you.
What’s your return policy? I’ve had bad luck with bras online.
Totally fair. If it’s not love at first wear, no worries. You’ve got 30 days to try it, and if it’s not working for you, just get in touch with us — we’ll help you sort it out. No drama, no pressure, no questions asked.
How should I wash and care for my Magic Bra?

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.
This sports bra is the best I've ever bought. It's very comfortable and stays in place. It offers high-impact support while feeling soft on the skin. It is a perfect fit for me. I love it and have replaced my regular bras with this one. I plan to buy more in different colors. I'm very impressed and happy with this purchase.
If you’re looking for a supportive front-zip bra, this is it. I usually stick to underwires for the structure, but the support here is so good I don't even miss the wire. It’s well-constructed with really nice fabric—definitely a win. I'll be back for more!
It holds everything in place perfectly while keeping a natural silhouette. The front zipper is a total game-changer for convenience, and I love how the material provides great coverage without feeling bulky. Definitely a win—I'll be ordering more for sure.
I can actually take full deep breaths. No compression chest pain here.
It's honestly better than my old Nike one, and that's saying a lot.
Didn't expect to love it as much as I do. Might actually toss the rest of my sports bras.
I love that I can unzip it right after a sweaty run. No peeling off stuck fabric. Bliss.
Honestly? I didn't think a zip-up bra could be this comfortable. No more weird twisting to get it off when I'm sweaty , just unzip and breathe.
No underwire, no pain, no nonsense. Just comfort that works.
The crossback is super flattering. Makes me feel like my posture improved somehow.
