Getting your bra size

Step 1: Measure your Underbust Circumference at it's tightest, the circumference right under your busts.

Now you got your band size, we need to know your cup size.

Step 2: Measure your Overbust Circumference, the circumference of your bust at the fullest point.
To get your cup size, let’s do a simple math based on the 2 measurements you have taken earlier. 
Overbust Circumference -  Underbust Circumference = Difference
Now you have the difference, this determines your cup size.


Viola! Now you have your bra size!
