The perfect bra fit isn’t the holy grail, but it’s almost as hard to find. Most women would agree that it’s harder to find the right size in a bra than in any other clothing item. There’s no fail-proof bra size calculator, but finding your right size does start with taking your measurements. It only takes a few minutes. Really. There’s always going to be some trial and error involved and the size you get is just a starting point.
When your bra size is right, you look taller, your waist looks thinner and your clothes fit better. The right bra size may even relieve shoulder and back discomfort. So just do the measuring, okay!
Bra fit factors
Different factors such as breast shape and firmness as well as measurements will determine your ideal bra size. The easiest of these factors is measuring yourself with as much accuracy as possible to make sure that the bras you buy and wear will fit you. The tape measure is not the ultimate authority but it’s a good guide. You body type has an impact on your ultimate size as a bony ribcage may feel uncomfortable with a snug band and have to go up a band size whereas someone with more flesh around the ribcage may compress more and need to go down a band size for support. The firmness of your breast tissue can also have mean that you have to go up or down a cup size because the softer tissue compresses more and the firmer tissue might need more space to feel comfortable,
Measuring the band size (under bust measurement) correctly is important if you want to end up with a bra that fits comfortably and offers enough support and security for your breasts. The band of your bra is responsible for supplying the majority of the support your bra provides. If it fits too loosely, it won’t be able to offer enough support, which can lead to bouncing, discomfort, and long-term sagging.
Measuring for a bra
To calculate your bra size, you will need a soft measuring tape, and for best results, either remove your bra or wear the bra that fits you best.
First find your Band Measurement (under bust) by pulling the tape snugly directly underneath your breasts on the rib cage. Make that the tape is level all the way around your torso. Next find your Bust Measurement (over bust) by measuring over the fullest part of your breasts.
The band size in inches will determine your UK/US band size which means that if your measurement is 35/36 inches around the under bust you can will start by trying on a 36?? bra. To figure out the ??, we need to calculate the cup size by subtracting the band size (not under bust measurement) from the over bust measurement. For example if your ribcage measured 33 inches (34 Band) and you measured 39 inches around your bustline, then the result would be 5 not 6.
Cups sizes in go up for each inch so each number is a cup size. In UK sizing it generally goes like this A,B,C,D,DD,E,F,FF,G,GG, H,HH,J,JJ,K,KK so a 5 inch difference would be a DD cup size. For these example measurements you can start by trying on 36DD bras
Always check the brand’s sizing because some brands can be slightly inconsistent. Other brands might skip some of those letters, or substitute DDD for E, or something, so double check to make sure that you are buying the size you think you are! In addition, some brands or styles may run large or small and you may have to adjust accordingly.
