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 plunge bra is designed with a snug, secure band and structured cups. Because band and cup fit independently, choosing the right combination is important for the best support.
- Start with your band: Choose the band size closest to your underbust measurement. It should feel snug and secure without digging in or moving when you do.
- Cups feel tight or you have spillage? Keep your band size and go up one cup size.
- Cups gap at the top? Try a smaller cup size. This can also mean the cup shape may not be the best match for your breast shape.
- Band feels loose or moves? Try a smaller band size rather than sizing the entire bra up.
- Between cup sizes? We recommend choosing the larger cup size for more coverage.
- Best for A–C cups: This low-profile plunge style is designed primarily for UK A–C cups. If you have a fuller or heavier bust and prefer stronger coverage and support, a full-coverage style may be a better choice.
Still unsure? Contact Customer Support before ordering and we’ll help you choose the right band and cup combination.

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 know if I’ve picked the right band and cup size?
For the best fit, use your underbust measurement for your band size and your bust measurement for your cup size rather than relying only on your usual bra size. The band should feel snug and secure without digging in. If the cups feel tight or you have spillage, go up in the cup while keeping your band size the same. If the band feels loose or moves when you do, choose a smaller band.
Does this bra run true to size?
This style has a snug, structured fit designed to help it stay secure without straps. We recommend using your underbust measurement to choose your band and your fullest bust measurement to choose your cup, rather than relying only on your usual bra size. If you’re between cup sizes, choose the larger cup.
What should I do if the cups feel too small or I’m spilling out?
Keep the same band size and try one cup size larger. For example, if the band on a 36B feels secure but the cups feel tight, try a 36C rather than increasing the whole bra size.
What if the band feels loose or the bra moves when I wear it?
The band should fit snugly around your rib cage to keep a strapless bra secure. If it feels loose or slides when you move, try a smaller band size while adjusting the cup size if needed.
What if there is a gap at the top of the cup?
Gapping can mean the cup is too large or the cup shape isn't the best match for your bust. Try a smaller cup size first while keeping your band size the same.
I'm between two cup sizes. Which should I choose?
We recommend choosing the larger cup size, especially if you prefer more coverage or tend to experience spillage.

Customers praised this strapless front buckle bra for its excellent fit and all-day support. Many said "it stays in place" and "doesn't slip down," with the silicone grip proving effective. The front closure and natural lift received high marks. Some noted sizing runs slightly small, recommending sizing up on the band. A few found it tight initially but comfortable once adjusted.

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!!!!!
I purchased this for my maternity photoshoot and I am so happy with it! Its comfortable and supportive. The straps can be added when needed, but I use it mostly as a strapless. It stays in place and gives the right amount of lift.
I bought this to use as a strapless bra. It provides great lift and fits me well! Also, it feels comfortable. Im excited to use this bra in the standard way as well.
I wear a 34A and got the gray 34A, and it fit perfectly! This is a must-have for any summer dresses. I will be ordering more colors once they have my size in stock!
Super nice, I loved it! The fabric is very good and looks like high quality. I definitely recommend it because, for the price, the quality is amazing!
This strapless bra stays in place and is really comfortable. I bought it for a dress with a plunging neckline, and it works perfectly. Its also soft and feels great against my skin.
Ok. I read the reviews and decided to try it anyway. I want you to know I am NOT the person who wears bras really ever. I prefer sports bras. However Ive gotten to the point both in age and professionally that I needed more structure because I am a huge fan of dresses. This is bra is GOOD. Even though I dont wear them I have an 18 year old that loves bras and really needs them.
So far this is the best strapless bra I have ordered I absolutely love it. It also doesnt slip down or anything while wearing it
This bra fits perfectly and stays in place all day. The grip around the band makes a huge difference, and I am so happy with how comfortable it is. Definitely my go-to bra now!
My gosh... this fits perfectly! I lost a ton of weight and needed a push-up beige bra for my bridal shower outfit and strapless tops. I wore this all 4th of July weekend and never once felt like I was going to droop or fall out! Its really amazing for the price! Im buying a second one so I have a spare.
This is hands down the best strapless front closure bra Ive tried. It stays in place all day, has a smooth, seamless fit under clothes, and provides just the right amount of support and lift.
I loved it! I had tried other fasteners without strips but none like this. I asked for one more size, as many commented that it was small; It didn't fit big and fit well with the elastic it brings, but if I had asked for my size I would have I recommend it, it is very good quality and arrived very fast.
I love this bra i purchased it for a wedding where I was wearing a strapless gown, and i'm impressed with the quality. I was the MOH so I needed something that was reliable because I didn't want to be seen pulling my bra up all day, and these did not disappoint. I got the 34A which was perfect on, and they stayed in place even through the dancing - from morning until late night these were solid and I almost forget I was wearing anything.
Received yesterday and trust me waiting for your order to arrive was worth it ❤️. It is all you want in a strapless bra. wonderful, awesome, am falling short of words. I will recommend to all my girlfrns for sure❤️
