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.

For the best fit and comfort, our pre-shrunk fabric ensures your size stays consistent wash after wash.
Bra sizes can vary by style. For your best fit, please use our size chart before ordering.

Why Your T-Shirt Bras Keep Failing You (And What to Do About It)
You know that frustration when you find a shirt you love, put it on, and immediately see your bra lines screaming through the fabric? When you spend all day tugging, adjusting, and secretly counting the minutes until you can finally take it off?
You've tried the "seamless" bras. The "invisible" ones. The ones that promised they'd disappear under your clothes and feel comfortable all day. And every single time, it's the same story: visible lines, gaping cups that somehow still dig into your ribs, or that stiff, suffocating feeling that makes you want to rip it off the second you get home.
Here's the truth they don't tell you: Most T-shirt bras are designed with thick, rigid molded cups that simply don't work with real bodies. They're built in one standard "shallow" shape that pushes away from your chest, creating those visible lines and forcing the underwire to dig into your ribs. It's not your body that's the problem—it's the design.
That's why we engineered the Magic Bra Light Lift differently. Instead of thick, stiff padding, we use ultra-thin cup technology that actually conforms to your unique shape. Think of it like this: traditional bras try to force your body into their shape. Our ultra-thin cups adapt to yours.
The result? You get the seamless, invisible look you were promised—but with actual comfort that lasts all day. No more visible lines under your favorite tops. No more underwire torture at 3 PM. No more racing to take it off the second you walk through your door.
Imagine putting on a bra in the morning and actually forgetting you're wearing it. Going through your entire day—presentations, lunch meetings, errands, dinner with friends—without once thinking about adjusting, tugging, or counting down until you can change. That's not too much to ask. That's what your bra should have been doing all along.
Made from a silky-smooth blend of 85% polyamide and 15% elastane, the Magic Bra Light Lift gives you natural shape, gentle support, and all-day breathability. Available in sophisticated black, vibrant orange, elegant purple, stylish beige, and classic white.
You deserve a bra that just works—without pain, without compromise, without thinking about it.

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.
