Understanding Bra Cup Sizes
Did you know that many women are walking around wearing the wrong bra size? It’s true! And it’s not just about comfort; a properly fitted bra can make a world of difference in how you feel and even how you stand.
This article will break down everything you need to know about bra cup sizes, including what they mean and why they matter. We’ll also cover:
- How to measure yourself accurately
- Common fit problems and how to solve them
So, let’s get started and find the perfect fit for you!
Understanding bra sizing components
Bra sizes aren’t as simple as small, medium, and large. They’re based on two measurements: your band size and your cup size. Here’s how to figure out what those measurements mean.
Band size: The foundation of fit
The band size is the number in your bra size, such as 32, 34, or 36. In the U.S., this number corresponds to the circumference around your chest, just under your breasts, in inches. In Europe, the number is based on the centimeter measurement.
To get an accurate band measurement, measure snugly around your rib cage, right under your breasts. Round up to the nearest whole number, and then add inches, depending on which sizing method you’re using.
Cup size: Determining breast volume
The cup size is the letter in your bra size, such as A, B, C, or D. The cup size indicates the difference between your bust measurement (around the fullest part of your breasts) and your band measurement.
Each inch of difference between those two measurements typically corresponds to one cup size. But keep in mind that a “D” cup on a 32 band is a smaller volume than a “D” cup on a 36 band.
How to accurately measure your bra size
If you’re tired of bras that dig, gap, or generally feel uncomfortable, here’s how to get a more precise fit.
What you’ll need
Grab a soft measuring tape, a well-fitting non-padded bra, and a mirror. You’ll also want a bra size chart handy, which you can find online.
Measuring your band size
Wrap the measuring tape directly under your bust, making sure the tape is level all the way around. Pull the tape so it’s snug but not too tight, and round up to the closest whole number.
Measuring your bust size
Wrap the measuring tape around the fullest part of your bust, keeping the tape level. Again, you want the tape to be snug but not compressing your breasts.
Calculating your cup size
Subtract your band size from your bust size. The difference determines your cup size, using the bra size chart.
- 1-inch difference = A cup
- 2-inch difference = B cup
- 3-inch difference = C cup
- 4-inch difference = D cup
- And so on
Understanding the difference in cup sizes
Bra sizes can be confusing, but the cup size is simply based on the difference between your bust measurement and your band size. Each letter corresponds to the number of inches of difference between those two measurements. Here’s a quick guide:
A cup vs. B cup
An A cup means your bust measurement is one inch larger than your band size. A B cup means your bust is two inches larger than your band size. How do they compare? An A cup bra offers less coverage and support than a B cup.
B cup vs. C cup
A C cup means your bust measurement is three inches larger than your band size. A C cup bra will give you more support and coverage than a B cup. If you’re spilling out of your B cup, a C cup is likely a better fit.
C cup vs. D cup
A D cup means your bust measurement is four inches larger than your band size. Compared to a C cup, a D cup offers even more support and coverage. Despite some misconceptions, a D cup isn’t necessarily “large.” It simply means there’s a four-inch difference between your bust and band measurements.
Common bra fit issues and solutions
It’s not always easy to find a bra that fits well. Here are some common problems and how to solve them:
- Too small a cup: You’ll know the cup is too small if you’re spilling out of the bra or feel squeezed. The solution is simple: Go up a cup size.
- Too large a cup: If there’s gaping or wrinkling in the cup fabric, or if the straps keep slipping off your shoulders, the cup is probably too big. Try going down a cup size, and adjust the straps.
- Too tight a band: A band that’s too tight will dig into your skin, feel uncomfortable, and create back fat spillage. Try going up a band size, or add a bra extender to give yourself a little more room.
- Too loose a band: If the bra band rides up in the back, or if you’re not getting enough support, the band is likely too loose. Try going down a band size, or tighten the band if possible.
The impact of breast shape and style on bra fit
Not all breasts are created equal. In fact, there are many different breast shapes, including round breasts, athletic breasts, east-west breasts, asymmetric breasts, bell-shaped breasts, and relaxed breasts.
When you’re shopping for bras, it’s important to keep your particular shape in mind.
Here are some general recommendations:
- If you have round breasts, plunge bras can be a great choice.
- If you have athletic breasts, you might like the support and shaping provided by a sports bra.
- If your breasts are fuller on the bottom, a balconette bra may be the most comfortable.
Considering your breast shape can help you find a bra that’s both comfortable and supportive.
International bra sizing
If you’re traveling or shopping online, it’s important to know that bra sizes aren’t universal.
US vs. European sizing
One key difference between US and European sizing is that band sizes are measured in inches in the US, but in centimeters in Europe. Also, the cup letter progressions don’t always match up.
Other international sizing systems
France, Spain, Italy, Australia, and New Zealand all have their own sizing systems. Because of this, you’ll want to know how to convert your size when you’re buying a bra from an international seller.
Websites like Bare Necessities offer handy conversion charts, so you can make sure to order the right size.
Closing Thoughts
Finding the right bra can be a game-changer! We’ve covered how to measure yourself accurately, decode bra cup sizes, and address common fit problems like spillage or gaping. Remember, your bra size isn’t set in stone and can change with weight fluctuations, pregnancy, or even just the style of the bra.
The most important thing is to prioritize comfort and support. Don’t settle for a bra that digs, pinches, or doesn’t provide the lift you need.
Make it a habit to regularly check the fit of your bras. And don’t hesitate to seek out a professional fitting if you’re unsure. A well-fitting bra is an investment in your comfort and confidence!
