Around 80% of women are wearing the wrong size bra. As we age, our bodies change. This is why it is important that you measure your bra size each year or during your pregnancy or breastfeeding. If you get it right, you can improve your posture, appearance and look. It is important to find a bra that is a perfect size for you. Follow these steps to find your bra size, but be aware that it is not always accurate.


Stand with your arms resting by your side and take a measurement around your body, directly below the bust. Make sure the tape is right under your breasts, is straight all the way around and is as tight as possible. This is how the under band of the bra will fit, so the tape should be tight, but not uncomfortable. It’s best to do this measurement while you are not wearing a bra. Round the fractional measurements to the nearest whole number. If that number is odd, add 5. If it is even, add 4. (For example, if you measured to 30 1/4″, you would round it up to 31, then add 5, leaving you with a 36 band measurement). This measurement is your UNDERBUST.


Standing straight, with your arms at your side, measure at the fullest part of your bust, usually over the nipple, (while wearing a non-padded bra) making sure the measuring tape is parallel with the ground and not binding. Round the fractional measurements to the nearest whole number. This measurement is your OVERBUST.


Take your band measurements and subtract it from your cup measurement. Find the difference on the  the chart to your cup size. (For example, cup size 38 minus band size 36 is 2, so that’s a B cup). After 38 bra size, the band size should be the closest higher even number to your actual measurement. So, 41.5” is a 42 band. A 41” measurement is a 42 band.

Any bra sizing where a tape measure is involved will not be totally accurate. Factors such as the firmness of your breasts, the narrowness of your shoulders and the broadness of your neck can affect your measurements.
