fit the best so far
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.

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.

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.

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.
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.
Let's be honest—most "comfortable" bras still make you count the hours until you can rip them off. This one's different. CloudSoft™ fabric breathes instead of suffocating you. The wide band stays put without rolling. Nothing digs. Nothing shifts. Most customers tell us they forget they're wearing it—and that's exactly the point. When you stop thinking about your bra, you know it's actually working.
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.
Sizing anxiety is real—we've been there. Check the Fit section for guidance specific to this style. If you're stuck between sizes, message us with your usual size and what's failed you before. We'll help you find the right fit without the guesswork. And if it's not perfect? Easy exchanges, no drama.
We get it—trust is earned. Try it for 30 days. If you're not in love from the first wear, reach out and we'll help you exchange or return it. Free returns, no guilt trips, no interrogation. We'd rather you find your perfect fit than keep the wrong one.
Most wireless bras rely on compression—they squeeze you flat instead of actually lifting. That's why they feel like a chest prison. Our MagicLift™ design uses structural support from the band and cup construction to lift and shape without wires or the suffocating squeeze. It's real support without the torture. Still skeptical? That's what the 30-day trial is for.
Looking for wire-free comfort? Seamless smoothing? Extra lift? We've got styles for each. Check our fit guide on the product page—it's based on real customer feedback, not generic charts. Or message us directly. We actually respond, and we'll help you find your match.
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.
These racerback sports bras provide excellent support and comfort for various activities, especially during summer. They come in a variety of colors and sizes, with some users noting color bleeding during washing. The snug fit is perfect for workouts and daily wear, with plans to reorder. However, the medium and large sizes may not be ideal for long runs.
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.
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.
Love these, but I want another color next time pleaseee!
Love the fit and color options! I got large, though I might try medium next time for more compression during runs. Still, very pleased and gave it 5 stars for overall comfort and price.
As a sporty woman, its tough finding supportive bras. The L fits me perfectly. These keep everything in place even during interval training. Ill definitely be ordering more from Magic Bra soon.
