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!
| 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.
This is what freedom feels like. No digging, no suffocating, no adjusting—just support that lets you forget you're wearing a bra at all.
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.

End the Torture. Wear Support That Actually Works.
You know the impossible choice: compression bras that lock things down but make you feel like you're trapped in a chest prison, gasping for air. Or "comfortable" styles that let you breathe but leave you bouncing painfully through every burpee.
Here's what's been holding you back: traditional sports bras rely on squeezing or sacrificing—neither solves the real problem. Our Wide-Strap Weight Distribution™ system spreads support across your entire upper back, eliminating the digging, bruising, and red marks of traditional straps. Anti-vibration construction stops painful bounce without compression suffocation. And the front zip means no more wrestling sweaty fabric off your body.
Support and comfort aren't opposites. You just needed a bra engineered to deliver both—from the first second you put it on.

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 this actually support me during high-impact workouts—like, really support me?
Yes—and we mean it. The wide crossback straps and anti-vibration construction are specifically engineered for running, jumping jacks, burpees, and everything in between. You get serious lockdown support without the compression suffocation that makes you feel like you're trapped in a chest prison. No more choosing between breathing and bounce control.
I've had sports bras where I literally can't breathe. Will this suffocate me?
Absolutely not. That trapped, claustrophobic feeling comes from compression bras that flatten everything into submission. Our design uses structural weight distribution instead of squeezing, so you get rock-solid stability without feeling like you're being strangled. You'll actually take full, deep breaths during cardio—the way it should be.
How do I take it off? Will it leave residue?
Gently peel from the outer edge—no ripping required. The silicone releases cleanly without pulling your skin or leaving sticky residue behind. Some find it easier to remove in a warm shower. Pro tip: Don't apply lotion before wearing—clean, dry skin helps it stick better and release easier.
How hard is it to get on and off? I've literally fought with sweaty sports bras.
The front zip changes everything. Pull it on, zip up—done in 2 seconds. After your workout when you're dripping? Unzip and slide it off. No wrestling match, no getting stuck halfway, no exhausting struggle. It's the feature customers rave about most because it ends one of the most annoying problems in the entire category.
Can I actually wear this all day, or just for workouts?
Both. Thousands of customers put it on in the morning and wear it straight through their workout, errands, and the rest of their day. It's supportive enough for high-impact exercise but so comfortable you'll genuinely forget you're wearing it. That's what happens when you engineer real support without compression torture.
I'm between sizes. What should I order?
Size up for comfort. The anti-vibration support and crossback structure work across a size range, so you'll still get excellent lockdown support in the larger size—just with a more comfortable, breathable fit. And if it's not right? Hassle-free returns, no questions asked.
What's your return policy? I've been burned by online bra shopping before.
We get it—online bra shopping can feel risky. That's why we offer hassle-free returns if the fit isn't perfect. No restocking fees, no drama, no judgment. We want you to love it from day one, but if it's not right, we'll make it right.
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.
I love this sports bra. It fits true to size for me and is very comfortable. I do rebounding so I needed a high impact bra with a lot of support for my bouncing girlies. This definitely accomplished that task. I also prefer the opening in the front which makes it so much easier to put on and take off. Loved it so much I bought another one in pink.
Those extra support panels is my favorite detail. They run from the band up to the under-bust to give you actual lift and a great shape, which is so rare for a sports bra. A quick pro-tip: always wash your bras in a mesh bag to keep them safe from snags, and never put them in a hot dryer. If you want to keep that amazing support, air drying is the only way to go!
Out of the entire Magic Bra line, this sports bra is definitely my top pick! I’m a 36B and the medium offers a flawless fit. The front zipper is super convenient, and I love the protective cover at the top. It not only prevents snags and feels comfortable against the skin, but it also creates a smooth, seamless look under my workout tops.
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.
