Maternity Bras 101


Those same boobs you once tried desperately to get cleavage out of now seem destined for the cover of a Harloquin romance novel. So what exactly do you do with your new, er, friends?

The key to staying comfortable throughout your pregnancy and your expanding breast size is to get a proper fitting maternity bra. In fact, chances are you’ll need several different sizes throughout your pregnancy, with breasts typically increasing 2-4 cup sizes during those nine months.

To ensure a proper fit, use this easy guide for determining your correct maternity bra size:


To work out your band size (the number part) take a tape measure and place it around your body so that it lies flat just under your bust. Take this measurement in inches, rounding up if the circumference comes out as an uneven number (i.e. if the actual measurement is 37” your correct band size would be ‘38’). You now have your band size.

To work out your cup size you should take the tape measure and place it around the widest part of your bust whilst wearing a well fitted, unpadded bra. Again, take this measurement in inches. You will then need to work out the difference between this measurement and your band size to find out your cup size. Every inch of difference between these two measurements is equivalent to an increase of one cup size.

e.g. Say your band size is 36 inches and your bust measurement is 39 inches, the difference between the two is 3 inches. Using the table below you can see that this is equivalent to a C cup size, so your overall bra size would be 36C.
