Was a bit worried the smaller size might be tight, but it's actually just right. Still relaxed without looking scruffy.

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! We recommend measuring this part in Inches and converting it to CMs.
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.

Sculpted Support, Strapless Freedom, & Unshakable Confidence
From elegant evenings to everyday glam, this posture-sculpting bra wraps you in confidence, lifts you beautifully, and stays invisible under every curve-hugging outfit.
This corset-style posture bra runs large in the band, so ordering your usual bra size may feel loose and unsupportive. For the best lift and secure strapless hold, size down one band size first (for example, 36C → 34C).
The cups are designed to compress and push up for shaping; size up in the cup only if you prefer a more relaxed feel.
If you are between sizes, choose the smaller band for better support and cleavage.
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.

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?

This bra is highly praised for its comfort, support, and flattering lift. It caters well to those with wider breasts and includes a subtle padding. The company is appreciated for its customer service. However, some may find the price higher than competitors.

If you're between sizes, go for the smaller one for sure. It's already got a roomy fit.
- Lucy L. Lucy25-12-2025
Went down a size and it's finally the look I was after.

Runs pretty big, followed the advice to size down and I'm chuffed. New favourite piece.
- Lauren L. Lauren15-12-2025
I normally wear a Large, but the Medium fits exactly how I wanted. Material's top quality, just mind the sizing.
- Nicola N. Nicola14-12-2025
Had to send the first one back as it was far too big, but the smaller size fits perfectly. Dead comfy.
- Megan M. Megan07-12-2025
Really nice piece, just bear the measurements in mind. Sizing down made all the difference.
- Gemma G. Gemma05-12-2025
A bit bigger than expected at first, but honestly? It's perfect.
- Emily E. Emily04-12-2025
It's cut quite oversized, so unless you're after a really baggy look, go down a size. Exchange was dead easy too.
