It can be tricky to find a bra that fits well, so it’s no wonder that so many women are unsure of their true size. Wearing the wrong size bra can cause a host of problems, from uncomfortable chafing to back and neck pain, not to mention a less than flattering silhouette. Follow these simple steps to find out what size bra you really need.

How to Measure Your Bra Size

To find your bra size, you will need a measuring tape and a mirror. First, put on a non-padded bra that fits you well. Take a deep breath in and exhale, then measure around your chest at the band level. The tape should be level and snug. Round up to the nearest whole number. This is your band size.

Step One: Measure Your Band Size

To measure your band size, wrap a measuring tape around your rib cage, just underneath your bust. The measuring tape should be level and snug. Round to the nearest whole number. If the number is even, add four inches. If it’s odd, add five. This is your band size.

For example, if you measured 32 inches, you would add four inches for a total band size of 36 (32 + 4 = 36). If you measured 33 inches, you would add five inches for a total band size of 38 (33 + 5 = 38).

Step Two: Measure Your Bust Size

To measure your bust size, wrap the measuring tape around your back and bring it across the fullest part of your chest. Make sure the tape is level all the way around and isn’t too tight. Round up to the nearest whole inch and write down that number. That’s your bust size!

Now that you have your band size and bust size, you can use a bra size chart to figure out your bra size. If you’re between sizes or if one breast is a different size than the other, don’t worry! You can always use a bra fitting service or ask a salesperson for help finding the right size for you.

Step Three: Determine Your Cup Size

Now that you have your band size, it’s time to find your cup size. To do this, stand in front of a mirror and wrap the measuring tape around your back at band level. Make sure the tape is snug but not too tight, then allow it to rest on the fullest part of your bust. Be sure not to press too hard into your skin or pull the tape too taut—you should be able to slide a finger between the tape and your body. Once you have your measurement, use this conversion chart to determine your cup size.

If Your Band Size Is…And Your Bust Measurement Is…Then Your Cup Size Is…

34 inches less than 34 inches A

34 inches 34 inches A or B (we recommend trying both sizes)

36 inches 36 inches B or C (we recommend trying both sizes)

38 inches 38 inches C or D (we recommend trying both sizes)

40 inches 40 inches D or DD/E (we recommend trying both sizes)

42+ inches 42+ inches DD or greater (we recommend starting with DD/E and going from there)

How to Find the Right Bra Fit

It’s estimated that around 80% of women are wearing the wrong size bra. The most common complaint from women is that their bras are uncomfortable. This is usually because they are either too tight or too loose. If you’re not sure what size you need, don’t worry. There are a few easy ways to figure it out. Let’s get started.

Step One: Find a Bra That Fits Your Band

Finding a bra that fits your band is essential to finding a well-fitting bra. All other aspects of fit depend on the band — straps can be adjusted, cups can often be deepened or widened, but if the band is too big or too small, the bra simply won’t fit.

There are a few ways to tell if your band is too big or too small:
-The band should be level with the front of your body. If it rides up in the back, it’s too big.
-You should be able to comfortably fit two fingers under the band. If you can’t, it’s too tight.
-The band should not be so loose that it slides around on your body.

If you think your band may be too big or too small, try going down a size or up a size and see how it feels. You may be surprised at how much difference a small change can make in the overall fit of your bra!

Step Two: Make Sure the Cups Fit

The cups should enclose the breasts without causing them to spill over or bulge. You may need to go up a cup size (or two) if you find yourself constantly pulling at your bra or if your breast tissue is spilling over the top or sides of the cups. Conversely, if your cups seem roomy, you may be able to solve the problem by going down a cup size.

There are also a few other signs that can indicate that your cups are too small or too large:
– If you have wrinkles in the cups (even when you adjust the straps), they’re probably too big.
– If your breasts bulge over the top or sides of the cups, they’re probably too small.
– If the underwire isn’t flat against your chest or hurts when you wear it, try going up a cup size (or two).

Step Three: Check the Center Panel

Now that you’ve got the band snug and comfortable, it’s time to check the center panel. This is the part of the bra that sits between your breasts and often has a decorative element like a bow or gem. It should lay flat against your chest and be level with the ground. If it’s not, then you need a different size.

Step Four: Ensure the Straps Fit

After putting the bra on and adjusting the band, it’s time to focus on the straps. First, make sure they’re not too loose by tighten them until they’re snug but not tight. If you can slide more than two fingers underneath, they’re too loose.

The straps should also be comfortable without digging into your shoulders. If they are, try loosening them a bit until you find the right balance of comfort and support. Once you have the straps adjusted, bend over to make sure your breasts are staying in place. If they’re falling out or if you have to readjust them after every few minutes, the band is too loose and you need a smaller size.
