Getting the right fit doesn't need to be hard, let us help you make sure you get the right fit.
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!
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.

Real support. Real comfort. Real freedom. All in one bra.
Finding Your Perfect Fit:
This sports bra runs true to size with a snug, supportive fit. The longline band should sit firmly below your bust without rolling or riding up. The longline band should sit firmly below your bust, staying smooth without rolling or riding up.
The racerback straps are made to stay in place and evenly distribute weight across your shoulders—secure but never digging. Built-in padding provides modest coverage and natural shaping for a flattering look and comfortable feel.
If you’re between sizes, size up for a little extra breathing room or size down for a more compressive fit. The right fit should feel supportive, balanced, and effortlessly comfortable all day long.
You know that sinking feeling when you're trying on yet another sports bra, hoping this one will be different? You tighten the straps enough to get support, but now they're cutting into your shoulders. You loosen them, and suddenly everything's bouncing. You try a tighter band for more hold, but now you literally can't breathe. And you're stuck wondering: why is it so hard to find a sports bra that just... works?
Here's what most brands won't tell you. The problem isn't you. It's that most sports bras are designed using the same tired "shrink it and pink it" approach—basically taking men's athletic wear, making it smaller, and slapping on some feminine colors. They rely on simple compression (smashing everything down) and generic S/M/L sizing that completely ignores the fundamental relationship between band size and cup size. This forces you into an impossible choice: Do you want to breathe, or do you want support? Do you want your straps to stay put, or do you want them not to dig in? You shouldn't have to choose.
That's exactly why we engineered the Magic Racerback Longline Sports Bra differently. Instead of compression alone, we use an encapsulation design that lifts and separates—giving you real support without creating that dreaded uniboob or suffocating feeling. The longline band (not your shoulders) does 80% of the support work, anchoring everything in place so your straps never dig or slip. The racerback cut distributes weight evenly across your back and gives your ribcage room to expand fully. And the breathable nylon-spandex blend wicks sweat instantly, so you stay cool even during the toughest workouts.
Imagine this: You put on your sports bra in the morning, and you actually forget you're wearing it. No adjusting the straps at your desk. No peeling it off the second you walk through the door. No red marks, no pain, no fighting to catch your breath. Just comfortable, reliable support that moves with you—whether you're crushing a workout, running errands, or curled up on the couch. You look in the mirror and see a smooth, flattering silhouette. You feel lifted, supported, and confident. And you think: "This is what a sports bra should feel like."
Over 2,000 women have already made the switch, and they're never going back to their old bras. As one customer put it: "I didn't know sports bras could actually be comfortable until I tried this one. I wear it all day and forget it's even there." Another said: "Finally, a bra that supports me without suffocating me. The longline band is a game-changer—my shoulders don't hurt anymore."
You deserve a sports bra that works as hard as you do—without making you work against it. One that supports you, breathes with you, and moves with you. Every single day.

Step 1: Waist
First, find your natural waist where your body indents at the sides. Wrap measuring tape around this area, then measure 5 cm below - this is where your pants typically sit. Keep the tape snug but comfortable - this is your waist measurement.
Step 2: Hip
Next, locate the fullest part of your hips - this will be 6" to 9" below your natural waist, depending on your height. Wrap the measuring tape around this area, keeping it snug but not tight - this is your hip measurement.
If you're between sizes, always choose the larger size for comfort. Your panties should lay smoothly against your skin without digging or pinching.
Finding your perfect fit starts with accurate measurements. Getting this right ensures comfort and prevents potential health issues. Here's your comprehensive guide to measuring correctly:
DO's
DON'Ts
Supportive answers for your most common bra dilemmas.
Yes. The magic is in the longline band and racerback design working together. The extended band (sitting below your bust) anchors everything in place and does 80% of the support work, while the wide racerback straps distribute the remaining weight evenly across your back. This means real support for running, jumping, and HIIT—without the bounce or pain.
Not at all. We designed this specifically to solve the suffocation problem. The racerback cut and scoop neckline give your lungs full room to expand, and the nylon-spandex blend stretches with you—not against you. You get supportive hold without compression that restricts breathing. It's the "I forgot I'm wearing a bra" feeling you've been searching for.
Start with your usual size—this bra runs true to size with a snug, supportive fit. The key is the band: it should sit firmly below your bust without rolling, riding up, or cutting in. If your band ever feels loose or shifts during movement, size down. If it digs in or you can't breathe comfortably, size up. Still unsure? Contact us and we'll help you find your perfect fit.
Neither. That's the whole point of the racerback design. Traditional bras put all the weight on two narrow shoulder straps, which either dig in (if they're tight enough to support) or slip down (if they're loose). Our wide, cushioned racerback distributes weight across your entire upper back, so you get the support without the digging or slipping. It's the best of both worlds.
Nope. The seamless construction and bonded edges mean no visible bra lines—even under your tightest tops. The racerback design stays hidden under tanks and tees, and the smooth back panel eliminates any bulging or cutting. You'll get a clean, polished silhouette from every angle.
Most sports bras use compression alone (smashing everything down) and rely on S/M/L sizing that doesn't account for different body types. We use encapsulation design that lifts and separates, plus a longline band that actually supports. You're not forced to choose between breathing and support, or between straps that dig and straps that slip. Everything just... works.
You can absolutely wear it all day. In fact, most of our customers do. It's supportive enough for intense workouts but comfortable enough for running errands, working from home, or lounging. The breathable fabric keeps you cool, and the seamless design looks great under everything. It's the "one bra does it all" solution.
We offer easy returns within 30 days of purchase. If the fit isn't right or you're not completely satisfied, just reach out to our customer service team and we'll help you process a return or exchange. We want you to love your Magic Bra, and we'll make sure you get the right fit.

I didn’t realize how bad my old sports bras were until I tried this one. It’s like night and day.
I wore it hiking and forgot I was even wearing a bra. And trust me,that’s rare for me.
Surprisingly holds up for everything except super high-impact workouts. For everyday wear,it’s perfect.
It’s good,but I wish there were more colors. The fit is great,just want more options.
I like it,but the band felt a little snug at first. It loosened up after a couple wears though.
The neckline is modest enough but still feminine. Perfect balance.
I love that I can wear it all day without getting those angry shoulder marks.
The black one creates such a sleek silhouette under clothes. Super flattering.
This bra doesn’t fight me when I breathe deeply. I can expand my ribs fully and still feel supported.
The support is strong enough for medium-impact workouts without feeling like a straightjacket.
It doesn’t roll up,even during stretching or bending. That alone deserves applause.
I’ve washed it several times and the fabric hasn’t pilled or stretched out. Still looks brand new.
My favorite part is the way the straps sit. Zero digging,zero slipping,just… there,doing their job.
The light blue color is so pretty in person,soft but sporty.
Feels lightweight but still secure. Like it’s doing its job quietly in the background.
The longline fit smooths my torso a bit,which is a nice bonus when I’m wearing fitted tops.
I like that it doesn’t slide up when I lift my arms. Some bras act like they’re trying to escape.
