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.

Seamless, wire-free comfort and invisible support for every moment.
Perfect for work, weekends, or anytime you want to look flawless and feel truly comfortable, move freely, stay cool, and enjoy soft support that disappears under every outfit.
This seamless T-shirt bra features a firm, high-compression, wire-free design for a smooth, supportive fit. Because the fabric provides structured compression, it is designed to feel firmer than a standard everyday bra.
CRITICAL FIT & SIZING GUIDANCE FOR UK BUYERS:
- Measure Before Ordering: Use both your underbust and bust measurements and compare them with the size chart. Do not rely only on your usual bra or clothing size.
- Avoid Choosing Too Small: The bra is designed to provide firm compression, but it should not feel painfully tight or overly restrictive. If you are between sizes, choose the larger size for greater comfort and cup coverage.
- Check Your Cup Fit: The cups should comfortably contain your bust without excessive spillage, pressure, or gaping. If your bust measurement is near the upper end of the recommended range, prioritise adequate cup room and coverage rather than choosing a smaller size for extra compression.
- Fuller Bust or Broad Back: If you have a fuller bust or broader back, consider the larger size when your measurements fall between ranges. This helps provide sufficient room for the bust while maintaining a comfortable fit.
- Set the Right Support Expectation: This is a wire-free compression bra, designed for smoothing, shaping, and everyday support. It is not intended to provide the same level of lift or rigid support as a wired or heavily structured push-up bra.

Fabric & Care
Fabric & Care
Fabric Blend & Technical Build
- Body Material: 80% High-Density Smooth Performance Nylon, 20% Spandex Compression Elastic Core.
- Cup Architecture: Wire-free high-apex cups with integrated, fixed medium foam contour shaping padding.
- Hardware Core: Traditional extra-wide multi-row back hook-and-eye tension clasp array.
- Edge Detailing: Heat-bonded, laser-cut seamless scalloped trim lines.
Intimate Apparel Care Instructions To preserve the high-tension compression memory of the performance nylon, follow these simple tips:
- Hand Wash Recommended: Wash gently in cool water with mild soap to maintain the structural integrity of the built-in cup padding.
- Fasten Back Hooks: Always fasten the back hook array before washing to ensure the metal clips do not catch or tear the seamless scalloped edges.
- Air Dry Only: Lay flat to dry in the shade. Never use bleach or high-heat tumble dryers, as intense heat will degrade the spandex elasticity and cause the seamless bonded seams to separate.

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 choose the right size for the best fit and support?
For the best fit, measure both your underbust and bust before ordering and use our size chart as your guide. Choosing the correct size helps provide the best comfort, support, and coverage. If you're between sizes or unsure which size is right for you, our Customer Support team is happy to provide a personalized sizing recommendation before you place your order.
How do I know which size to choose?
Measure your underbust and bust before ordering and use our size chart to find your best fit. The correct size provides the best comfort and support. If you're unsure, contact our Customer Support team before purchasing for personalized sizing advice.
Is the back closure easy to fasten?
This style uses a multi-row hook-and-eye back closure it's what gives you that secure, no-slip hold. Most customers find it easy once they get the hang of it, but if you have limited hand dexterity or prefer something faster to fasten, our Front Closure Bras collection (like the Magic Strapless Front Buckle Bra) might be a better fit.
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's your return policy? I've had bad luck with bras online.
Totally fair—we know you've experienced some horror stories. Here's the deal: you get a full 30 days to wear it, wash it, live in it. If it's not love? Return or exchange, no questions asked. We want you to feel confident ordering, not anxious. The only way we grow is by making bras women actually keep—so you can shop with confidence every time.
How should I wash and care for my Magic Bra?
A little love goes a long way. Hand wash in cool water with gentle detergent for best results—or use a mesh laundry bag on the delicate cycle. Skip the dryer completely; lay flat or hang to dry. This keeps the CloudSoft™ fabric soft and the MagicLift™ support intact wash after wash. Treat it right, and your bra stays comfortable for years, not 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.

Very comfortable and it fits well but my only criticism is that the straps aren’t long enough.
Fits great, good quality and super comfortable! I can wear it all day and hardly notice it's on! It stretches nicely too. Really soft and durable material. Great value!
This bra truly is the most comfortable wireless bra I’ve ever owned. The wide band provides support where you need it. Love that the straps stay in place too—does not budge! I am a 34B and purchased the Small. The fit is perfect. Material is soft, smooth, seamless and of good quality. Can’t beat the price for ultimate comfort.
This bra is great quality and fits comfortably all day! It provides fantastic support that doesn't fade with wear.

I really like the appearance and the quality very good. The material is soft and would be very comfortable - if I could wear it. I wear a 36DDD in most other bra types. When I look at the size chart, it shows a Large would fit best. Yes, it fits well around my body.
I wish I had found the wireless bras earlier. Extremely comfortable and supportive.
Love this bra. Very comfortable & looks great under clothing.
I'm always dubious of buying bras from the Internet but giving this ago was the best thing. They are really soft material with lots of support and also have adjustable straps. I'm a UK 38C and bought the size recommended and fits perfectly, delivery was quite fast too.
I originally ordered the wrong size but magic bra checked my measurements and then ordered me the right size. They allowed me to keep the first order which I then donated. Very efficient and helpful service and the bras are pretty and comfortable.
This bra is a nice as I hoped it would be and I’ve immediately ordered another. Soft and smooth but without giving monoboob! And has really wide but soft straps, no digging in. Nice silhouette under a t shirt. I’m a 32DD and got the M. It’s super comfy round the back. I’ve ordered an L next as I’d like the cups a bit bigger.
Finally found a wireless bra that actually gives proper support. been wearing it daily and its so much more comfortable than my old underwire ones
seamless under everything
Breathable fabric is great especially in summer. doesnt get all sweaty like my other bras do
no wires digging in
really comfy
Got this after getting fed up with underwires and its brilliant. support is there but without the pain
invisible under fitted tops
Wireless but still shapes nicely which is hard to find. been looking for something like this for ages
soft material
Best wireless bra ive tried honestly. gives shape and support without feeling like youre wearing anything restrictive or uncomfortable
Love that its breathable cos i run hot and most bras make me sweaty. this one lets air through properly
good all day comfort
Great fit for larger sizes. Super comfortable and supportive.
I typically wear underwire bras but decided to try this one based on reviews. It is so soft, flattering, and supportive.
As a taller woman, I struggle with straps being too short, but this bra fixes that. The straps adjust and the material doesnt dig or roll. Wore it all night and didnt need to adjust once. Loved it so much I already bought another color.
This is the most comfortable bra Ive owned. Im usually a 12 to 14B, but it runs slightly big. I will size down to a small next time. The color is just as pictured.
I ordered an XL, and it fits like a dream. It is seamless, soft, and supportive without tags or wires. Covers underarm fat and has light padding that stays in place. Adjustable straps can even be crisscrossed. Easy to wash, and I will definitely get more.
I chose the medium in nude and couldnt be happier. Im between a 34C and 36C, and this fits perfectly. Tons of support without feeling like you are wearing a bra. Great quality and highly recommended!
The material is soft and supportive, with pretty scalloped cups and wide bands. Straps are adjustable and removable, making it versatile. Seamless design works well under tight tops. Overall, a great buy.
I was surprised by how good the quality and comfort were. This is easily the best bra Ive bought in years!
