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.

Love It the Moment You Clasp It
Most sports bras demand you choose: breathe or be supported. The Magic CloudSoft™ Racerback refuses that trade-off. Our MagicLift™ underband does the heavy lifting—literally—so straps don't dig trenches into your shoulders. CloudSoft™ fabric feels like relief, not restriction. No wires stabbing your ribs. No bands rolling up your back. No counting down until you can finally tear it off.
The stay-put Y-back disappears under tanks. The scoop neck covers without suffocating. This is the bra that ends the daily negotiation between your body and your clothes.
Finally—support that doesn't feel like punishment.

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—or is it just another "comfortable but useless" sports bra?
This isn't compression that smashes everything flat and calls it "support." Our StructuraLift™ wide band handles 80% of the work—the way proper bras are engineered—so you get real lift without straps digging into your shoulders. Whether you're a B cup or DD+, the weight gets distributed across your back, not concentrated in two thin lines cutting into your skin. Support and comfort aren't a trade-off here.
Why does this bra feel more supportive than a typical wireless bra?
That's the design working. The firm, posture-supportive fit is what gently nudges your shoulders back and takes the load off your neck and back; something a regular wireless bra simply can't do. It may feel slightly more secure than what you're used to at first. Give it a few minutes to settle, adjust the front hooks to your comfort, and most customers find it becomes their go-to all-day bra.
I have a larger bust. Will this actually work for me?
Absolutely. Most bras fail larger busts because they rely on straps—which dig, slip, and leave you in pain. Our wide underband construction means support comes from your band, not your shoulders. Larger-busted customers are actually some of our most enthusiastic reviewers because they've finally found support without the daily suffering.
"I'm larger-busted and scared I won't find my size. Do you actually have plus sizes?"
We hear this fear constantly and we built for it. Our extended size range accommodates larger busts and the fluctuations of pregnancy, engorgement, and nursing. Lightweight CloudSoft™ fabric stretches without losing support. Check our size guide, and know this bra grows with you from second trimester through weaning.
"What if it doesn't fit? I've had bad luck with bras online."
Fair concern. Online bra shopping feels risky, especially when your body keeps changing. You've got 30 days to wear it and decide. If the size shifts or it's not right, reach out. We'll exchange or refund. No drama, no hoops.
I've wasted so much money on bras. Why should I believe this one is different?
Because we built this for women who've tried everything and given up. The difference is in the engineering—MagicLift™ supports without the crush, and CloudSoft™ delivers softness you can actually feel. But we're not asking you to take our word for it. Try it for 30 days. If it doesn't deliver, send it back. Our reviews are full of former skeptics who said this exact thing—and never went back.
How do I know which style is right for me?
This seamless plunge bra is perfect if you wear low-cut tops, want invisible support under fitted clothes, or just need everyday comfort without wires stabbing you. Our fit guide breaks down each style by what you actually need—not confusing technical specs. Still unsure? Send us a message. We'll help you find your match based on what you're looking for.
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.
Ive tried many sports bras, and these fit the best so far. I sized down to small even though the chart said medium. They stretch a bit over time, so starting snug was a smart move. Great support and value.
Ive owned these for a few week and just bought more this day. Theyre stretchy, durable, and easy to take off post-workout. I wear a large. The colors are still bright, and they wash up great!
Easier to put on than most over-the-head styles. Offers great support and even gives a flattering shape. Im not a runner, but for daily use, its ideal.
I got the small size. The fit is great and looks amazing on. These are super comfy and give the support I need for the gym!
Offers solid support for my workouts. The racerback fit is secure and doesnt chafe. Its breathable, stretchy, and keeps everything in place, even during high-impact moves.
These Magic Racerback Sports Bras fit snug but not tight. They lift and hold everything in place. I jump, and they dont budge. Foam pads stay in place during wear, and even after washing, they hold up. These are high-impact bras for my size.
I ordered a large. Its slightly roomy but still wearable. Super comfy, with a nice snug hold. The blue is cute, and I think itll hold up long-term.
I bought both large and medium. I wore the medium for a half marathon, great support. The large is better for lounging or lighter workouts. Definitely replacing my old ones with more from Magic Bra.
Ive been looking for a bra that fits my bust for months. I took a chance on the Magic Racerback Sports Summer Bra, and Im so glad I did. Its super comfortable and the color options are lovely. Easily my best purchase this year.
