Let's Get You Fitted!
1. Measure your under bust.
Measure around the top of your rib cage under your breasts - if you're between measurements round up to the nearest half inch eg 30.25 round up to 30.5
2. Measure the circumference of your breasts across your nipple.
(You may bend over if that helps)
Measure the circumference across your nipples and again if you are between sizes you may round up to the nearest inch eg 34.75 round up to 35.
The difference between the measurements in inches is your bra cup size eg from the instances above 35- 30.5 = 4.5 inches.
Each inch is a cup size so
1 INCH= Cup size A
2 INCHES= Cup size B
3 INCHES= Cup size C
4 INCHES= Cup size D
5 INCHES= Cup size E / DD
6 INCHES= Cup size F/DDD
7 INCHES= Cup size G
8 INCHES= Cup size H
Since the example had a result of 4.5 inches, you may round up to the nearest cup size for a full bra or scale down for a bra with more cleavage.
