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.

Less digging. Less dreading. Less daily negotiation with your underwear. Just support that feels like a deep breath from the moment you put it on.
The Posture Bra has a firm, supportive band with wire-free cups and a front-fastening design. For the best fit, check both your underbust and fullest bust measurements before ordering.
- Cup Fit: The cups can feel smaller than expected, especially on fuller busts. If the band fits well but you have spillage, tightness, or breast tissue sitting above the cup, choose a larger cup size rather than automatically increasing the band size.
- Band Fit: The band should feel secure and supportive without being painfully tight. If the band already fits comfortably, keep your band size and adjust the cup size separately if you need more room.
- Posture & Support: This bra is designed to provide gentle back smoothing, shoulder alignment, and everyday support. It is not a medical posture-correction device and does not provide rigid or therapeutic posture support.
- Lift: The wire-free design gives natural shaping and everyday lift, rather than the stronger lift of a structured underwired push-up bra.
- Fabric Feel: This style contains nylon, giving the bra a smooth, stretchy, close-fitting feel. Please check the material composition before ordering if you are sensitive to synthetic fabrics.
- Front Fastening: The bra uses multiple front hook-and-eye fasteners for a secure fit. Customers with limited hand mobility or difficulty using small fasteners may find the closure more challenging.
Still unsure which size to choose?Please contact our Customer Service team with your usual bra size, underbust measurement, and fullest bust measurement. We’ll help guide you to the best band and cup size before you order.

All-Day Stretch-Elastic Leisure Support

Experience a new standard of daily comfort and effortless alignment. The Posture Bra Wireless Lift Up is engineered as a premium, entirely wireless leisure foundation designed to ease daily shoulder strain and smooth your silhouette without the painful digging of traditional underwires or the restrictive squeeze of rigid posture braces.
Crafted from a soft, high-density stretch-elastic nylon matrix, this everyday support top features an unlined, unpadded double-layered cup design that molds gently to your natural shape. By utilizing an extra-wide back panel with integrated cross-tension elastic bands, it delivers a continuous, gentle reminder for your shoulders to sit naturally back, keeping you feeling comfortably aligned, entirely smooth, and unrestricted from morning to night.
Fabric & Care
Fabric & Care
Fabric & Technical Build
- Material Core: 88% High-Density Premium Nylon, 12% Spandex Performance Stretch Matrix.
- Cup Architecture: Wire-free, unpadded, and unlined double-layered flexible compression cups (no removable pad inserts).
- Hardware Configuration: Vertical 6-tier front hook-and-eye closure column paired with multi-tier flat shoulder-strap hook selectors.
- Support Profile: Soft-elastic leisure and comfort alignment (not a rigid orthopedic medical brace).
Intimate Apparel Care Instructions To preserve the high-tension elastic memory of the criss-cross alignment bands, follow these simple care steps:
- Hand Wash Recommended: Wash gently in cool water with a mild detergent to protect the soft knit fibers and maximize garment lifespan.
- Fasten Hooks Before Washing: Secure the front 6-hook column before washing to prevent the metal eyelets from snaging the delicate performance mesh.
- Air Dry Only: Lay flat to dry in the shade. Avoid bleach, fabric softeners, and high-heat tumble dryers to prevent the spandex core from losing its stretch retention.

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 best size for the perfect fit?
For the best fit, we recommend using both your bust and underbust measurements with our size guide before ordering. Because the Posture Bra is designed to provide supportive lift and gentle posture support, it has a naturally snug fit. If you're between sizes, have a fuller bust, or prefer a more relaxed feel, we recommend choosing the larger size.
What if I'm between sizes or not sure what to get?
If you're between two sizes, we recommend selecting the larger size. This helps ensure a comfortable fit while still giving you the support and lift the bra is designed to provide.
Does this bra run true to size?
It runs tight, especially through the cup. We recommend ordering one size larger than your usual. If you're between sizes, always take the bigger one.
The band fits but the cups feel tight — do I size up?
Yes. This is the most common fit issue we see. The cups run smaller than the band, so if the band is comfortable but the cups feel tight or you're spilling over the top, go up one size. The next size gives you more cup room, and the band has plenty of stretch to stay comfortable.
How should it feel when it fits correctly?
Snug across the back — that's what creates the smoothing and the posture cue, and it settles after a wear or two. The cups should sit flat with no gaping or spillage. If it's digging into your ribs or the cups feel squashed, it's too small. Exchange it for the next size up rather than sending it back.
Will this help with back pain or posture problems?
This is a soft, wire-free comfort bra that offers a gentle posture cue — the criss-cross back encourages your shoulders to sit back naturally. It is not a posture corrector, and it is not a medical or post-surgical garment. If you need clinical support, please speak to your healthcare provider.
How does the front closure work?
Six hooks fasten at the front, so there's no reaching behind your back. Fasten it on the loosest setting first and work in as it settles.

Wireless posture bra praised for exceptional comfort and back support. Customers said "the lift is honestly better than bras ive paid way more for" and noted reduced pain. Sizing runs small—many recommend sizing up in cup or band. Front closure praised for ease. Some desire more padding or breast separation. "Very comfortable and supportive" all-day wear.

This is the best bra I have ever worn. It is so good I had to take a picture for this review. I ordered another one after I received the first because I was so pleased with the fit. Perfect. The support is excellent. I change bras when I get home from work to be more comfortable because the support in these bras is so great. This bra really does help your posture.
I love this wire-free posture support bra. It is very comfortable, moves and stretches easily, the shoulder straps are wide, adjustable, and well padded, especially for larger sizes. Everything is smooth and cushioned against the skin. It's great for everyday wear and I gladly recommend this product. I plan to get rid of several other styles/brands that I've been wearing (enduring) and order more of these. Thanks.
not true to size, ordered my normal n it was to small. went up one n its perfect 😌
went up a size n so glad i did. the lift is honestly better than bras ive paid way more for, no wires, no diggin, n it holds everythin in place all day 🙌
Good for pilates etc, but will not wear ebery day
Exactly what l need easy to put on & gives ma a good shape.
Very comfortable and supportive. Good design.
nearly ordered my usual n im glad i didnt. messaged them first cos im fuller in the bust n they said go up on the cup, keep the band. spot on 👍
Very comfortable bras. Well designed and easy to wear. Would recommend..
This bra is exactly what I’ve been looking for! It provides fabulous, excellent support. I’m very happy—I already bought two more. It fits perfectly, holds me securely, has fantastic back support, and the wide straps are comfortable without any wires. I’m so impressed!
i always just go off my band size when i buy bras, never really thought about the cup. with this one the cup matters just as much. measured my bust properly, went for more cup room n it fits so much better
I’ve tried many bras to find one that is comfortable and doesn't rub in the armpit area, and this one is a keeper. The quality is excellent, it's super adjustable, and it stays perfectly in place without moving around. Works great for my narrow shoulders.
Very comfy,have bought Three .Will buy again.
Lighter material than anticipated but very comfortable.
Finally found a bra that is supportive and comfortable enough for all-day wear. Very pleased with the quality!
the band felt secure from the off but i was spillin out the top of the cups. swapped for the same band with a bigger cup n its so much comfier now. dont change both, its just the cup
I find these bra's very comfortable and none restrictive. I have three now and love them
This bra was a cracking surprise! I usually struggle to find a decent, comfy fit, but these have blown me away. I picked one up in Beige, size 42B, and I’ve just ordered another two in white and black.
I’m chuffed with the front closure! There are plenty of hooks for a properly firm feel, and while there’s no fiddly underwire, it’s still fully supportive. It’s usually a right nightmare to find a good fit as most bras have cups far too large for my smaller chest. The straps adjust using separate hooks and eyes for an even better bespoke fit. Spot on!
The breathable fabric feels absolutely brilliant and never pulls or tugs on the skin. It provides instant relief for the shoulders, and the adjustability is spot on for different outfits.
Do note that the front closure is a touch visible under tight tops and takes a bit of a faff to fasten, but the trade off for the superb back support and 'no-dig' fit around the arms is completely worth it. Proper high-quality find, this!
Honestly I doubted how much this would help, but it’s been such a crazy difference. I hadn’t realised just how much my posture was getting dragged down until I put this on. The improvement was immediate, and it’s also an immediate decline when I take it off!
My back did hurt a bit on the first day for a couple of hours as my body got used to actually being upright. But it stopped pretty quickly and my back feels so so much better in general now. The bra is also so much more comfortable than I thought it would be, I don’t really want to wear any other bra now! Basically, if you think your boobs are causing bad posture, get this!!
measured my underbust n my fullest bust before pickin a size which i never normally bother with. glad i did tho, it stopped me goin to small in the cup 😌 sits properly now, no diggin in anywhere
Fits perfectly true to size for a 34D. It offers a lovely smooth, natural look under clothes rather than loads of cleavage, which makes it grand for everyday use.
The material is properly sturdy and it has definitely helped me stand a fair bit taller throughout the day. If you’re after a well-built, posture-supporting bra that actually fits exactly as it ought to, this is the business!
band was fine, cup was too small. kept my band n went up one cup n thats it sorted, no spillage 😌
I find this bra comfortable and so easy wear. It is very easy to fasten, so much better than back fastening bras.
I found this bra very comfy when I had it I didn’t think it would fit but when on I found it a very comfy fit support without pain lovely
runs small! sized up n now it fits perfect 😌
honestly this has helped my back pain so much. been wearing it to work every day and my posture is way better
comfy all day
posture support actually works which i didnt expect. no wires poking either
good for back pain
wireless but still supportive
