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.

Stop Blaming Your Body. Your Current Bra Was Never Built for You.
You know the routine: buy the strapless bra, spend the night yanking it up, end the evening with a bra around your waist and red marks in your ribs. Then you wonder if you're just the wrong shape for strapless. You're not. The bra is the problem.
Here's what's been holding you back: most strapless bras are designed for a 34B and "scaled up" for plus sizes. A single horizontal band can't fight gravity on a fuller bust, so it slides within minutes.
Our Crossback Lockdown system fixes this at the structural level. Two wide bands cross over each other and anchor at side hooks, gripping your back from two angles instead of one. The downward pull of a fuller bust gets redirected sideways and upward, where the bra holds. Pair that with molded push-up cups that lift from underneath, and you get real shape, real security, zero compromise.
Strapless dresses without dread. Push-up shape without underwire pain. A bra you forget you're even wearing. Finally engineered for your body, not in spite of it.
Fabric & Care
Fabric & Care
Fabrics:
75% Nylon, 25% Spandex, performance-engineered, comfort-obsessed.
What This Means for You:
The high-spandex blend gives you four-way stretch that grips without squeezing, so the crossback band stays locked in without leaving red marks or cutting off your circulation.
Nylon adds the smooth, second-skin feel that makes the scalloped edges disappear under bodycon, silk, and slinky fabrics. The combination is what lets the bra hold a fuller bust securely while still feeling soft enough to wear all day.
Care Instructions:
Hand wash cold or machine wash cold in a lingerie bag. Hang dry. Do not bleach, do not tumble dry, do not iron.
Pro tip: hand washing extends the life of the elastic and keeps the crossback tension intact.
Why It Matters:
Quality construction means your bra holds its shape, support, and grip wash after wash. The bands keep their crossback tension, the cups keep their structure, and the lockdown that made you buy it stays exactly that. This bra is built to last, not to disappoint you in three weeks.

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 on a fuller bust, or is this another "scaled up" bra that slides down?
Yes, it stays up, and the crossback design is exactly why. Most strapless bras rely on one horizontal band that gets overwhelmed by gravity within minutes on a fuller bust. Our crossing bands grip from two angles and anchor at side hooks, redistributing weight across your entire upper back. It physically can't slide the way a traditional strapless does.
I've sworn off strapless bras because they always end up around my waist. What makes this different?
We hear this constantly, and we get it. The reason this one works is structural, not a marketing claim. The wide crossing bands create two anchor points instead of one, so the downward pull of a fuller bust gets redirected sideways and held. You don't need to tug, hoick, or readjust all night because the bra has nowhere to slide to.
Will the band dig in or leave red marks on my ribs?
No. There's no underwire and no boning, so nothing is poking into your sides. The wide crossback design distributes pressure across a much larger surface area instead of concentrating it on one tight band. You get firm hold without the red trenches, bruises, or end-of-night discomfort.
Does it really give push-up shape, or will I look flat or pointy?
Real push-up shape. The molded cups lift from underneath and hold a rounded silhouette, so you get genuine cleavage without the pointy or uniboob look that ruins most strapless bras. The cups are structured but soft, so the shape stays natural, not forced.
Will it show under tight or thin clothing?
No. The scalloped, raw-cut edges sit flat against your skin instead of creating a visible bra line. There are no seams, no ridges, and no telltale outline through bodycon, silk, or slinky fabrics. It's designed to disappear under whatever you put on top.
I'm between sizes. Should I size up or down?
Size up for comfort. The crossback structure grips firmly across the size range, so you'll still get excellent lockdown support in the larger size, just with a more relaxed band feel. And if it isn't right, hassle-free returns, no questions asked.
What's your return policy? I've been scammed by online bra shopping before.
We get it. Online bra shopping, especially in plus sizes, is risky. That's why we offer hassle-free returns if the fit isn't right. No drama, no judgment. We want you to love it from day one, but if it isn't your bra, we'll make it right.

Flattering cup shape, doesn't slip or shift around.
Excellent fit, they hold the girls perfectly.
These are perfect.
Impressed! I’m a DD and it held the girls up without sagging or squashing them!
It definitely stays up well. No pulling it up or fiddling around with it required. Great support and the quality is good too.
Great quality.
I’m a big girl and I wear a 4XL. I got this to go with an underbust corset for a low cut cosplay, and it is solid. If I were going to use the straps, I’d probably want something a bit thicker than the ones it comes with, but as a strapless, it works a treat! I almost spent way more on a big name brand, so I’m glad I took a chance on this.
The fit was great supportive and comfy.
Love this bra!! It's so comfy and I'd buy more if this one didn't already do the job for literally everything.
I'm so glad I stumbled across this bra. It doesn't feel like your standard bra no straps or annoying clasps. It’s like a comfy tube top but with actual support. It stays in place and gives great coverage. If you get the right size, you won't be pulling it up constantly; you might even forget you're wearing it!
This is my first time buying a strapless bra. I've tried on so many in department stores and been disappointed every time. I took a chance ordering this one based on the photos and reviews, and I'm stoked I did! I’m a 3XL (42DDD in other styles). Obviously, you won't get the same lift as a bra with straps, but this strapless is comfortable and stays put. Excellent value, too.
I wore this strapless bra all day and was actually surprised by how comfy and secure it felt. It stayed put without slipping, gave me a smooth look under my clothes, and didn't feel tight at all. The material is soft and breathable honestly, you almost forget you've got it on. A really good option for an everyday strapless.
This strapless bra is dead comfy. It’s got plenty of support and the fabric is really stretchy and breathable. I find it actually gives me a bit of a lift and looks great, which I love.
Best strapless bra I've ever owned! It’s comfy as, and it doesn't slip or dig in at all. It doesn't give a massive amount of push up or lift, but it supports you well without even feeling like a strapless. The price is a total bargain, too!
Extremely comfortable! It didn't slip down like some do, so I didn't feel the need to keep tugging at it. Felt like I wasn't wearing anything at all.
Very comfy and true to size. Decent support too.
Great stuff. It was comfortable as. Not 100% sure if I grabbed the right size, but it worked for me regardless.
Very comfy, stayed put all night. Exactly what I was after. Great price too!!
This is easily the best strapless bra I’ve ever found. It’s dead comfy but still really supportive. I’m a 38DD and this thing is great. I originally bought it for a holiday, but I’ll definitely be getting more now.
GRAB THIS BRA. I was a bit hesitant because I wasn't sure if it’d actually fit me. I’m a bit of a weird size my breasts go down and out in different directions rather than forward (honestly, think of a big bloke lol). I’ve got really broad shoulders, weigh between 145155kg, and I always struggle to find bras. I’ve actually been going braless for the last 6 or 7 years because it’s so hard to find anything comfortable. Usually, putting a bra on feels awful and everything just starts weighing me down.
This bra, though, feels lovely. It doesn’t force them together in a tight squeeze, it passes the bounce test (the full tiptoes to heavy drop, and they’re heavy loads lol!), it’s not uncomfortable at all, and it really helps keep them in place.
One of the big draws for Magic Bra is that they offer a huge range of sizes that a lot of other brands just don't do. I own a couple of their bits and pieces and absolutely love them.
The bra is really nice and sturdy. The fabric is soft and stretchy but still feels true to size. It doesn't give you heaps of definition, but it definitely keeps the girls supported and leaves your back lookin' smooth! It stays in place too, which is a big win. Very nice!
This is a comfy bra. The sizing is generous, but it actually makes your back look better and gives the bust a decent lift.
So comfy, I'm stoked with the size and quality. It's exactly like the ad says. Fantastic!
I just got this in the mail and I was bracing for disappointment like every other bra, but this one is wonderful.
I'm definitely hanging onto this one because the material feels lovely and it's a quality bit of gear. It’s got a really free, relaxed fit nothing like those restrictive ones you usually find. It moves around a bit more than I thought it would, but it’s a comfy choice for those days you want a lighter feel. Stoked to add it to the collection!
This bra is a really good shout if you're after something comfy and reliable without the straps. The silicone grip inside the band means it stays put all day, so you’re not constantly worrying about it slipping down or shifting. It’s made from soft, comfy material that feels great on, making it perfect for sleeveless or off the shoulder tops. The wavy edge is a nice touch and helps it sit well. It’s easy to get on and off and actually gives decent support for a strapless. Overall, it’s a simple, comfy bit of gear that works for everyday or when you’re dressing up. Definitely a great choice if you want something that stays in place and feels good all day long.

I’ve been looking for a Plus Size Strapless Seamless Push Up Bra my entire life. It’s comfy as and actually stays put. I’ve always hated those bulky pads in the dozens of other strapless bras I’ve bought over the years, but this one is spot on.
Top notch model and it's easy as to wear.
I'm actually amazed. I was bracing for disappointment, but I'm happy to say this bra is great. It’s really supportive and comfy; I’m glad I took a chance and grabbed it.
