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.

Experience the freedom of strapless style—without the fear.
Powered by MagicLift™ support and CloudSoft™ comfort, this bra stays put through every movement, every celebration, every wow moment. All-day lift, zero slip, pure confidence.
This low-profile fashion plunge piece is uniquely engineered with a highly flexible, low-walled frame designed to stay hidden under special event outfits.
- Petite Busts (UK A & B Cups): Do not size up. Stay completely true to your tight, snug rib cage baseline measurement. If you match a 36A everyday high-street retail size, do not select a 38B; a firm, snug band is required to prevent the low-profile cup edges from gaping.
- DD+ CUP CAPACITY WARNING: This low-plunge style is structurally optimized specifically for UK A to C cups. If you have full, heavy, or sagging breast tissue above a standard D cup, this low-walled fashion frame will not provide enough vertical coverage or support. We highly recommend purchasing our full-coverage Posture Bra Wireless Lift Up for optimal containment and orthopedic lift.

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.

What customers love about it
We Get These Questions A Lot
Supportive answers for your most common bra dilemmas.
Will this actually stay up—or will I be tugging it all night like every other strapless bra?
Yes, it actually stays up—and here's why it's different. Most strapless bras use compression alone, which means they either slip or squeeze painfully. Our front-anchor buckle creates a central lock point that distributes pressure evenly across three zones, so you get security without the death grip.
I've tried 30+ strapless bras and they all failed. What makes this one actually different?
Here's the truth: 99% of strapless bras fail because they rely on a single compression point fighting gravity. Our front-anchor engineering creates multiple anchor zones working together—like a suspension bridge instead of a vice grip. It's not marketing speak; it's physics. Customers who'd "given up on strapless bras" tell us this is the first one that actually works. It's not magic—it's better engineering.
Will it show through my dress or look bulky?
Not a chance. The seamless cups and low-profile design disappear under everything—bodycon dresses, fitted tops, sheer fabrics, white clothing. No lines, no show-through, no awkward bumps or visible edges. It's engineered to be invisible while still giving you support and shape. If you can wear a regular bra under an outfit without it showing, this will work even better because there are no straps to hide.
Can I really trust this for my wedding/event? I can't risk it slipping.
Absolutely. This is exactly what our customers buy it for—weddings, galas, bridesmaid dresses, formal events. You'll dance, hug, raise your arms, and never think about it. No covert tugging. No bathroom adjustments. No anxiety spiral. The front-anchor design was engineered specifically for "all-day, all-night" high-stakes events where failure isn't an option. You'll be present and confident, not distracted and adjusting. That's the promise thousands of brides and bridesmaids confirm.
Will this work for my larger bust (DD+), or is it only for smaller sizes?
Honestly? This bra performs well for D and DD cups. The front buckle creates a secure, adjustable fit that many DD customers love—stays put without the death-grip discomfort. Our sizing goes up to F, so if you're in that range, you'll likely have a good experience. But if you're G+ looking for heavy-duty support, this style may not be your best match. We'd rather you find the right fit than buy and return.
But won't it dig into my ribs or leave red marks if it's that secure?
Nope. That's the entire point—we engineered our way out of that awful trade-off. Traditional strapless bras concentrate all grip pressure in one narrow band. The harder they grip, the more they dig. Our TrueGrip™ band distributes pressure across your entire ribcage, and CloudSoft™ padding protects where wires and boning typically bruise. You get security without the pain. Customers say things like "forgot I was wearing it by the second song" and "no marks when I took it off at midnight."
Will this actually stay up, or will it slip to my waist like every other strapless bra?
It stays. Thousands of customers have danced, jumped, and celebrated with their arms in the air without a single adjustment. One reviewer said: "Survived my entire wedding reception and didn't move once." Another: "I was doing the Y, hands in the air, feet hopping with my 40D self—this bra was NOT." That's the standard we hold ourselves to. Not "only had to pull up once" (which competitors celebrate). Zero adjustments.
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.
A well made, supportive and most important, comfortable bra.
I’m absolutely over the moon with this purchase. It’s a solid 10/10 for me. I’ll definitely be ordering a few more straight away!
Spot on for size, with a lovely wide band and it's properly comfortable. It even came with clear detachable straps, which is handy.
There are hook and eye closures across the front as well, just in case you want to up the ante with the cleavage. Top notch!
Blimey, what a result! I’ve avoided strapless my entire life because I’m lost without a bra, and strapless ones have never quite done the trick.
I’m 53, and while I’ve got a tiny frame, I’m a bit larger in the chest for my size mind you, they aren't massive, I’m just pint-sized. Finding a decent bra is always a proper struggle, but this one is a total win! Sorry, no photos! ;)
After some extensive research, I stumbled upon this brand. It is constructed of a soft material and is comfortable to wear. The size was perfect and easy to put on.
I found another bra from a different website that didnt come in time for the wedding I was going to this weekend. So I headed to trusty old Magic to help me out last minute. And HOT DAMN AM I GLAD I DID. This bra is amazing. When I opened the bag it and looked at it I didnt thing all the padding was necessary as I dont wear padded bras… holy crap. My boobs looked perfect. I was dancing for hours with this thing on and it didnt move. Its not very stretchy, which was good in my opinion because it didnt have much give to be able to slip down. My usual size 34D, but I used their size chart, which you should definitely check, as I came out to be a 36D for this bra. I measured with no bra on, and I was in between measurements, so I went down instead of up. Its so comfy and I love the front closure. The whole shape of the bra was on point. Couldnt be any happier! The next time I need one Ill be coming back here for sure. So go ahead.. measure those girls and BUY ITTTTT!!!!!
This is MAGIC!! It fits perfectly, lifts, and adds some volume to your chest. The best strapless I've ever had.
I love this bra so much, I bought another one! I have many expensive bras from Victorias Secret, and I prefer this one to all of those! The padding is just right, its comfortable, and it stays up!
I like it, it fits great
A good bra for the price. It holds well and doesnt slip. It has an additional adjustable clasp in the front and another strap included. I could have gone with a larger size for my V cup.
