DIY BRA SIZINGMeasuring yourself for your bra sizeGet out the measuring tape!
Before you shop for a bra, it's important that you know your measurements. STEP 1: MEASURE YOUR BAND SIZE
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. STEP 2: MEASURE YOUR CUP SIZEWhile 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.
|
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.
