Bra Fitting Guide
How to Find Your Ideal Bra Size
Your bra should look and feel great under your clothing and wearing the correct size plays a vital part in this. Not only does wearing the right sized bra make you feel more comfortable, it also can improve your posture and create the appearance of a smaller waist. Around 80% of women are wearing the wrong sized bra and don’t even realise. Knowing your bra size is important for so many reasons and whether you have small breasts or large breasts it is just as essential to make sure you are wearing the correct size. If you are really struggling to get a base size our measuring guide below will give you a rough estimate of your bra size but we would strongly recommend that you follow our top tips for a more accurate fit.
HOW TO MEASURE YOUR
Before you start make sure that you are either wearing a non-padded bra or no bra at all. Using a tape measure, measure in inches around your rib cage directly under your bust and below the underwire of the bra. If you find that your measurement is between sizes then you need to round down the size, for example if you measure 30 1/2 inches then round down to 30 inches.
IF YOUR MEASUREMENT IS AN EVEN NUMBER- ADD 4 INCHES
IF YOUR MEASUREMENT IS AN ODD NUMBER- ADD 5 INCHES
This will calculate your band/back size. For example, if your band/back measures at 30 inches you will add 4 inches which would make you a 34.
HOW TO MEASURE YOUR
Measure around the fullest part of your bust in inches ensuring that the tape measure is taught but not over stretched. When measuring your cup size you should always round up, so if you measure 34 ½ inches then round up to 35 inches. The number of inches difference between your band/back measurement and cup measurement will equal what cup size you are. Every inch difference equals one cup size up. For example:-
BAND SIZE 34 INCHES & FULLEST PART OF BUST 34 INCHES= A CUP
BAND SIZE 34 INCHES & FULLEST PART OF BUST 35 INCHES= B CUP
BAND SIZE 34 INCHES & FULLEST PART OF BUST 36 INCHES= C CUP

If the wires stand away from the body at the centre front or dig in at the underarm, a
larger cup size is needed. The centre panel should sit flat against your skin.
If the bust is bulging over the tops of the cups and/ or under the armpit then a larger
cup size is needed. There should be a smooth transition from bra to skin without
If the straps are digging into the shoulders, they are supporting too much weight on the
breasts and so the underband may not be giving enough support. A smaller back size
may be needed. The straps should feel comfortable all day long and not leave red marks
when taken off. You should be able to fit two fingers comfortably under the straps, if you
can fit anymore then the straps need to be tightened.
If the cups are wrinkling and there is space at the top and the sides of the cup, a
smaller cup size is needed. Your breasts should comfortably fill the cups of the bra without
If the cups lift away from the chest when the arms are lifted, then either a smaller back
size and/or a larger cup size is needed.
If the underband is riding up, the back size is too big. The band of the bra should sit
horizontally on your back.
If the band is uncomfortably tight and the hook and eye is straining, then the back
size is too small. You should be able to wear the bra on the middle or loosest setting. If
you are wearing the bra on the tightest setting you may need a smaller back size as over
time the bra will stretch.
It is quite common for a woman to have one breast bigger than the other. Sometimes
there is only a slight difference, but sometimes there is a cup size difference. It is
important to fit the bigger breast so that it is encased by the wire. The straps can be
adjusted so they are looser on the larger side and tighter on the smaller side to achieve
the best fit
