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.

Lifted, Supported, and Comfortable — Without Compromise
Love how it supports, shapes, and moves with you without crushing, digging, riding up, or making you overheated. One bra that finally does its job — so you can go live your life.
This bra is designed to fit your body—not generic size labels. Our real-size approach ensures every fit feels natural, supportive, and comfortable from the first wear. If you’re between sizes, we recommend sizing up for a little extra coverage and all-day comfort.
The wide straps should sit flat on your shoulders—if they roll or dig in, try the next size up. The band should feel snug but still allow deep breathing, and it should stay in place even when you raise your arms.

Support That Breathes With You
The Magic Wide-Strap Sports Bra gives you real, secure support without the breathless squeeze that makes you count down the hours until you can take it off. Our StructuraLift™ design distributes weight across a wider platform instead of squeezing everything down — so you can actually take a full breath during your workout.
The 2.5-inch ComfortGlide™ straps spread pressure across 40% more surface area (no more shoulder grooves that bruise). The square neckline disappears under tanks and tees. And the FlexMove™ fabric moves through 200+ positions without pulling.
Tested through 12-hour wear sessions. Loved by 50,000+ women who finally stopped counting down the minutes until they could rip it off.
This is the sports bra you put on and forget.
Fabric & Care

82.5% High-Performance Polyester Microfiber, 17.5% Medical-Grade Spandex
Fabric Technology:
- FlexMove™ 4-Way Stretch – Tested through 200+ movement positions for maximum flexibility without restriction
- BreatheFlow™ Moisture-Wicking – Microfiber channels pull sweat away from skin 3x faster than cotton; dries in under 45 minutes
- CoolTouch™ Breathable Construction – Prevents overheating even during high-intensity workouts or all-day wear
- SoftGuard™ Non-Irritating Finish – Dermatologist-tested; won't chafe even during 12+ hour wear sessions
- ColorLock™ Fade-Resistant Dye – Maintains vibrant color through 100+ wash cycles
Care Instructions:
- Machine wash cold (30°C/86°F) with similar colors
- Use mild, fragrance-free detergent
- Important: Avoid fabric softener—it reduces moisture-wicking performance by up to 60%
- Wash inside a mesh lingerie bag to protect fabric structure and extend lifespan
- Hang dry or tumble dry on low heat (not to exceed 60°C/140°F)
- Do not bleach, iron, or dry clean
Built to Last:
Triple-reinforced stitching at all high-stress points (underband, strap attachments, side seams). Independent lab testing confirms this bra maintains 95%+ of its original shape and elasticity even after 100 wash cycles. The high-grade polyester-spandex blend resists pilling, sagging, and loss of compression over time.
Durability Promise:
While most sports bras lose their support after 6-8 months of regular wear, our StructuraLift™ System is engineered to maintain full support for 18+ months with proper care.

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.
How do I know which size is right for me?
Our sizing follows standard sports bra sizing. Because this bra uses supportive compression, the band may feel snug at first to keep the bra secure during movement. If you prefer a more relaxed fit or are between sizes, consider sizing up.
What if it doesn't fit? I've wasted so much money on bras that didn't work.
We get it — buying bras online feels like gambling when you've been burned before. If your first size isn't right, exchange it for free. Not happy for any reason? Return within 30 days for a full refund. No hoops, no guilt trips. Over 94% keep their first order. If you're in the 6%, we've got you.
Will this work for my shallow or wide-set chest?
Yes—and we built it with you in mind. If you've struggled with the "pancake" problem where push-ups just add padding but no actual lift, the curved MagicLift™ wire creates shape by working with your natural structure, not fighting it. No more gaps at the top. No more padding that sits there doing nothing. Just real lift that actually works for your shape.
I always feel suffocated in sports bras. Will this be different?
Completely. That suffocating feeling comes from compression — bras that flatten your chest against your ribcage to stop bounce. We use structural support instead. Wide straps and a reinforced band hold you secure without squeezing you breathless. You'll actually breathe fully while staying supported.
Will it hold up during real workouts, not just light stretching?
Built for actual training. The integrated support system reduces bounce during HIIT, running, and jumping jacks — without brutal compression. Wide straps stay put during movement. No slipping, no sliding, no mid-workout adjustments. Tested by women who actually train, not models in a studio.
Can I wear this under regular clothes, or just to the gym?
Wear it everywhere. The square neckline stays invisible under tanks, tees, and square-neck tops. No weird bumps, no visible lines. Go from workout to errands to meeting friends without changing. It's the all-day bra — not a "gym bra" you rip off the second you walk through your door.
How do I wash it?
Machine wash cold, gentle cycle, hang dry or tumble low. Skip fabric softener (it reduces moisture-wicking). Lab-tested to retain elasticity after 500 washes. No stretching out. No padding going lumpy. No falling apart after a few months.
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.
Customers rave about this sports bra's "butter-soft" fabric and exceptional comfort. Most praise its supportive fit, flattering square neckline, and versatility for workouts or casual wear. The wide straps prevent shoulder pain and it "stays in place" during activity. Some note straps aren't adjustable, causing slight fit issues. Overall, shoppers say it rivals pricier brands at a fraction of the cost.

Absolutely stunning top! The fabric feels butter-soft and it fits perfectly.
This is so comfortable! The material is incredibly soft and offers a ton of support. I love the color, too!
I’m seriously impressed with this Magic Square Neck Sports Bra! The fabric is butter soft and feels amazing on the skin lightweight, smooth, and super comfortable. The quality honestly surprised me in the best way. It feels just as good (if not better) than some of the more expensive brands out there, so there’s really no need to spend a fortune when you can get this kind of quality.
This top feels so good on me! It fits great and provides excellent support. I’ve worn it while working out, running errands, and working, and I’ve received so many compliments! The material is soft, stretchy, and breathable. Great coverage!
This is hands-down one of the most comfortable and versatile tops I own. Magic Bra has quickly become my favorite brand – the quality rivals expensive name brands, but at a fraction of the price.The square neck design is flattering, the longline cut gives the right amount of coverage, and it’s supportive without feeling restrictive. The stretch makes it comfortable, and while I could get away with sizing up, I like that it makes me feel supported. It’s long enough to wear as a cropped tank with high-waisted bottoms – I’ve paired it with the skirt for a coordinated set, and I’ve also worn it with jean shorts. Since the fabric doesn’t have any shine, it easily passes as a casual cropped tank outside the gym.Fit is true to size and incredibly comfortable. Stylish, practical, and so easy to dress up or down – this is one of those tops I reach for constantly!
Love the quality of this sports bra, sizing is perfect! Only down fall for me is the straps are not adjustable, if they were the fit would be perfect!! It just tends to come down a little to low!!
It's so smooth under clothes. No lines, no weird bulges, just clean and sleek.
If comfort had a look, it'd be this bra.
It's stylish, breathable, and surprisingly supportive. Literally my new go-to.
Soft stretch that hugs, not strangles. Wore it from morning to night and didn't even notice.
Honestly, it's one of those bras you forget you're wearing, zero pinching, zero pressure, just comfort.
Wide straps = no shoulder pain. I didn't realize how much that mattered until now.
This square neckline is so flattering! I've been pairing it with everything from leggings to jeans.
Love how structured it looks without feeling stiff. It gives shape but still moves with me.
I've tried expensive ones that didn't feel this good. This one wins hands down.
I wear this way more than I should. It's too comfy to save just for workouts.
I was skeptical at first, but the wide straps changed my life. No digging, no shoulder marks.
It keeps everything lifted but not squished. Honestly the best combo I've tried.
I could live in this bra. It's comfy enough for yoga and stylish enough for errands.
It's the first bra I didn't want to rip off after a long day.
Even during long workouts, it stays dry and comfy. The moisture control is real.
It gives me such a nice shape under fitted tops, finally, no uniboob!
I've washed it five times already and it still looks brand new. Quality's legit.
The fabric feels expensive. Smooth, thick, and slightly cooling.
This bra fits like it was made for me. No adjusting, no slipping, just perfect all day.
It somehow manages to lift without feeling tight. That's rare.
No wires, no drama. Just clean support that works.
Usually bras this supportive feel restrictive, but this one breathes. Total game changer.
The fit around the ribcage is perfect, snug but never suffocating.
You can tell it's well designed, it just stays in place no matter what I'm doing.
The fabric feels buttery but firm enough to hold things in place. Super breathable too.
I get why everyone loves it. It feels tailored, like it molds to your body.
Didn't think I'd find a bra that actually stays put and feels this soft. It's like wearing air but with real support.
