How To Measure Your Bust and ensure that you have the correct bra sizes.
The first step is to measure your back size. It is often helpful if a friend or a partner can help you with this exercise.
Get a tape measure and place it under your breasts and around your body. For an everyday plus size bra with straps you add 4 inches to this measurement. So for example if you measure 34 inches around your body your back size is 38 inches.
The next step is to find out your correct cup size and here’s how you do that.
Take a tape measure and place it around the fullest part of your bust and all the way around your back.
The difference between this measurement and your back size is your cup size.
So for example if your back size is 36 inches and the measurement of the fullest part of your bust is 37 inches the difference between the two is 1.
Based on that difference your cup size is A. (see below for other sizes)
The difference between your over and under bust measurement will determine your cup size as follows:
1″ = A
2″ = B
3″ = C
4″ = D
5″ = DD
6″ = E
7″ = F
8″ = FF
9″ = G
10″ = GG
Getting a comfortable fit from your bra.
Once you put on your bra the band underneath the bust should be perfectly horizontal.
To ensure maximum comfort and the best fit you should be able to slide two fingers comfortably under the band.
Once you close the clasp at the back of your bra it should be flat against your body and should be beneath your shoulder blades.
Your breasts should be fully contained within the cup of the bra and not overhanging or protruding.
There should be no seams or wires digging into or resting on your breast tissue either at the front or at the back.
Your bra straps need to be secure but not too tight. As a test if you take your bra straps off your shoulder your bra should still support the bottom of your bust.
A well-fitting bra should be comfortable when walking, sitting or bending over.
Before you buy a new plus size bra, if possible try it on with the top that you plan to wear. If you look in a mirror your bust should be balanced and facing forward.
