Before you shop for a bra, it's important that you know your measurements.
To find your bra size, follow these quick and easy steps:
Wrap your measuring tape around your body at your under bust, making sure the tape is parallel with the ground and isn't loose or binding. Exhale completely to get the smallest band measurement possible.
If your band size exceeds 38", band size should be the closest higher even number to your actual measurement. For example, a 41" measurement would be a 42" band size.
While wearing a non-padded bra, stand up straight with your arms at your sides. Measure at the fullest part of your bust, making sure the measuring tape is parallel with the ground and not tight or binding. Round all fractional measurements to the nearest whole number.
Subtract your band size measurement (step 1) from your cup size measurement (step 2). Generally, for each inch difference, the cup goes up by one size. Here's an example:
Note: The cup size calculation starts falling apart at 4 inches larger than your band size. If you have pendulous breasts, your measurement will not be accurate.
A bra size is made up of two measurement components: band size (34, 36, 38, etc.) and cup size (A, B, C, etc.).
To find your correct bra size, begin by wearing your best fitting unpadded bra (not a minimizer or sports bra). If you are sagging in your bra, tighten the straps until the crest of your breasts is approximately halfway between your shoulder and your elbow. If possible, have someone else take your measurements. Not only is it faster, but it also tends to be more accurate.
If your measurement is: | 27 | 28 | 29 | 30 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 |
Then your band size is: | 30 | 30 | 32 | 32 | 34 | 34 | 36 | 36 | 38 | 38 | 38 | 38 |
If your measurement is higher than a 38" band size, round up to the nearest even number. For example, 41.5" is a 42 band size and 41" is also a 42 band size.
