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
Fabric & Care
Material Composition:
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.

Size Guide
Size Guide
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 Magic Bras actually support me — like, really support me?
Oh, 100%. Whether you’re a B cup or a G, Magic Bras are built to lift, shape, and hold you in — without squeezing or digging. They offer the kind of everyday support that moves with you, feels effortless, and still keeps everything right where it should be. You’ll feel the difference from the first wear.
Are they comfortable enough to wear all day?
Yep, that’s kind of our thing. We design every Magic Bra to feel like a second skin — breathable, soft, and smoothing in all the right places. No digging, no pinching, no “Can’t wait to take this off” energy. Just everyday confidence.
How do I know which style is right for me?
You don’t have to guess — that’s what we’re here for. From wireless comfort to sculpting support and everyday smoothing, we’ve got different styles to match what you need. Just check our fit guide or send us a quick message — we’ll help you find your favorite.
What makes it “magic” exactly?
It’s the way you feel when you wear it—and when you don’t have to think about it. Magic Bra lifts, smooths, and supports without the digging, tugging, or discomfort. You feel held, not restricted. That’s the kind of magic every woman deserves.
What if I’m between sizes or not sure what to get?
We’ve been there. Because sizing can vary between styles, we recommend checking The Fit section on each product page — it’s tailored for that specific bra. Our goal is to help you find a bra that feels like it was made just for you.
What’s your return policy? I’ve had bad luck with bras online.
Totally fair. If it’s not love at first wear, no worries. You’ve got 30 days to try it, and if it’s not working for you, just get in touch with us — we’ll help you sort it out. No drama, no pressure, no questions asked.
How should I wash and care for my Magic Bra?
Easy does it! We recommend cold water on a gentle cycle and air drying to keep the shape and softness just right. It only takes a little TLC to make the magic last.
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 exceptional comfort and support. They describe it as "weightless," "buttery smooth," and comfortable enough to wear all day.

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.

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.
Finally, a sports bra that doesn't squeeze my ribs every time I breathe. Freedom feels amazing.
The colour is so pretty in person, kind of soft and fresh, not too bright.
The support surprised me. It holds up even during cardio, but feels soft like loungewear.
That square neckline makes it look so elevated. I feel cute and supported.
