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!

A secure strapless fit starts with the right band and cup combination.
This strapless bra is designed to stay securely in place using a firm rib-cage anchor and high-stretch elastic band. Because there are no shoulder straps, the band should feel secure and supportive without being excessively loose or restrictive.
STRAPLESS FIT & SIZE GUIDE FOR UK BUYERS:
Measure Before Ordering: Measure your underbust and bust and compare both measurements with our size chart. Your measurements are more reliable than simply choosing your usual everyday bra size.
For a Secure Strapless Fit: The band should sit firmly around your rib cage and stay in place without riding up. If your usual band feels loose in strapless styles, choose the appropriate smaller band size based on your measurements. Do not automatically size down without checking the chart.
Between Two Sizes? If your measurements fall between two sizes, choose the size that provides enough band security while allowing sufficient cup coverage. If you prefer more comfort or have a fuller bust, choose the larger option rather than forcing yourself into a smaller size.
Cup Fit Matters: If the band feels secure but the cups feel too tight, spill over, or do not fully contain your bust, the cup size needs to be adjusted rather than simply tightening the band.
Sister Sizes: When changing to a smaller band size, increase the cup letter accordingly to maintain similar cup volume. For example, 34D → 32DD. Always use your measurements to confirm the best combination.
What the Fit Should Feel Like: The band should feel snug and secure, while the cups should comfortably contain your bust without excessive spillage, gaping, or pressure. A strapless bra needs a secure band to stay in place, but it should not feel uncomfortably tight.
For Fuller Busts: This style is designed to perform well for D and DD cups and is available up to F. If you are G+ and need heavy-duty support, this style may not be the best match.

Size guide
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.
Supportive answers for your most common bra dilemmas.
How do I choose the right size for the best fit?
For the best fit, measure both your band size and cup size before ordering and compare them with our Size Chart. If you're between band sizes or prefer a little extra comfort, we recommend choosing the larger band size. Our Customer Support team is always happy to help if you're unsure.
Does this bra run true to size?
This bra is designed for a secure, supportive fit. We recommend following our Size Chart and measuring both your band and cup size before ordering. If you're between band sizes, choosing the larger band size will provide a more comfortable fit.
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.
What if I'm between sizes or need help choosing?
If your measurements fall between two sizes, choose the size that provides enough band security while allowing sufficient cup coverage. If you prefer more comfort or have a fuller bust, choose the larger option rather than forcing yourself into a smaller size.
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 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'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 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.
Is this bra suitable for fuller busts (DD+)?
Yes! This bra is designed to support a range of cup sizes. For fuller busts, selecting the correct band and cup size is especially important to achieve the best lift, comfort, and support. We recommend checking the Size Chart before purchasing.
