Guide to Measuring the Bust
The first step in buying a brassiere is figuring out the correct bust size. The following is a guide which is used by many foundation manufacturers. Give it a try, it's fun.
Step #1
Take a firm measurement of the bust under the rib cage (in inches).
Step #2
If that number is even add 4 inches, if it is odd add 5 inches.
This is your actual bra size.
Step #3
Measure loosely around the fullest part of the bust.
Step #4
Figure the difference between the actual bra size and the fullest part of the bust measurement.
Use the "Cup-Size-O-Matic" (below) to get the cup size.
Cup-Size-O-Matic
If the difference is (in inches):
5" the cup size is...A
6" the cup size is...B
7" the cup size is...C
8" the cup size is...D
9" the cup size is...DD
10"the cup size is...E
EXAMPLE:
•1. Under the rib cage measurement=27
•2. Add 5 for bra size=32
•3. Fullest part of the bust measurement=33
•4. Difference between #1 & #3 is 6=B cup
•5. The Bra Size Is =32B
This scale is a basic guide which may vary according to flesh and bone structure.
