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.

Over 75,000 women have stopped the strapless bra hunt. This is the one that finally stayed put, felt amazing, and survived the entire wedding reception. Join them.
Fit Tip: If you’re between cup sizes on the chart, choose the larger cup. If your underbust measurement is close to the top of a band range, size up in the band; if it’s closer to the lower end, stay with the smaller band. This helps avoid the bra feeling too tight or too loose.

Finally—The Strapless Bra That Stays Up Without Leaving Marks
You know the nightmare. You've bought the strapless bras that slipped to your waist by the third dance—arms glued to your sides, terrified of public humiliation. You've tried the ones that promised "all-day support" but dug so viciously they left angry red marks on your ribs. You've endured boning that poked, bands that chafed you raw, and wires that bruised you so badly you couldn't wear any bra for days. And you've done all this torture just to prevent one thing: that catastrophic moment when your bra becomes a belt.
Here's what nobody tells you about why those bras failed you. Traditional strapless bras use a single-strategy approach—aggressive silicone gripping concentrated in one narrow band. The engineering creates an impossible trade-off: the harder they grip to prevent slipping, the more they dig into your ribs. It's not a design flaw. It's a fundamental limitation that every other brand has accepted. They've trained you to believe you can't have security and comfort. You have to choose.
That's the lie we engineered our way out of. The TrueGrip™ silicone band doesn't concentrate pressure—it distributes it across your entire ribcage. CloudSoft™ padding protects the exact spots where wires and boning typically dig and bruise. You get locked-in security without the torture. No choosing. No compromise. Both.
The MagicLift™ contoured cups solve the other betrayal—giving you natural, separated lift instead of that flat "uniboob" or pointy shape that makes you look worse than wearing nothing. And because we designed this for DD+ busts first (the ultimate engineering challenge), if it works on a 36H customer dancing all night—and it does—it'll absolutely work for you.
Imagine pulling that backless dress out of your closet without dread. Imagine dancing with your arms in the air, laughing genuinely, not monitoring your bra's position. Imagine coming home at midnight and realizing you forgot you were even wearing it—no red marks, no relief upon removal, just… nothing. That's not marketing language. That's verbatim from our customer reviews.
Thousands of women have stopped the hunt, stopped the anxiety, and started actually living in their clothes. One reviewer said it best: "Survived my entire wedding reception and didn't move once. Revolutionary." That's the standard.
No waiting. No wondering. No red marks. Just instant comfort from day one.

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 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.
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 work for my larger bust (DD+), or is it only for smaller sizes?
It's specifically engineered for DD+ busts—that's our proof of concept. If it can support and stay up on a 36H customer dancing all night (and it does), it'll definitely work for you. We use reinforced side boning, wider bands, and true-to-size cups designed for real bodies, not sample sizes. Extended sizing up to G means you don't have to compromise or "make do" anymore. The large-bust success isn't a niche feature—it's the engineering validation that proves this works for everyone.
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.
What makes this different from all the other strapless bras I've tried and returned?
Two things: engineering and honesty. Most strapless bras force you to choose between security and comfort—tight bands that dig, or soft bands that slip. We engineered TrueGrip™ silicone and CloudSoft™ padding to give you both. No lies, no "give it 180 days to break in," no celebrity markup. Just a strapless bra that actually works from day one. We don't ask you to wait, adjust, or tolerate pain. You'll feel the difference the moment you clasp it.
What if I'm between sizes or not sure which size 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 been burned by online bra shopping before.
Totally fair—we get it. You have 30 days to try it, and if it's not working, just contact us and we'll sort it out. No drama, no "restocking fees," no interrogation about why. We're that confident it'll work, but if it doesn't fit right, we'd rather help you than keep your money. Most people don't return it, though.
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.
