Follow these simple steps to ensure a perfect fit before making your purchase:

Step 1: Underbust Measurement:
Wrap a soft measuring tape snugly around your ribcage, just below your bust. Make sure the tape is parallel to the ground and take note of the measurement in inches or centimeters. Round the number to the nearest whole number.

Step 2: Band Size:
If the underbust measurement is an even number, this is your band size. For example, if your underbust measurement is 34 inches, your band size is 34. If the measurement is an odd number, add 1 inch to determine your band size. For instance, if the underbust measurement is 33 inches, your band size is 34.

Step 3: Bust Measurement:
Wrap the measuring tape around the fullest part of your bust, making sure it is parallel to the ground. Note down the measurement in inches or centimeters.

Cup Size Calculation:
Subtract your band size (step 2) from your bust measurement (step 3). The difference will determine your cup size. Use the following chart to find your cup size:

0 to 1-inch difference: AA cup
1-inch difference: A cup
2-inch difference: B cup
3-inch difference: C cup
4-inch difference: D cup
5-inch difference: DD or E cup
6-inch difference: DDD or F cup
7-inch difference: G cup
And so on…

If your current bra isn’t quite doing it for you, alternate sizes could be the answer! And, if the band is too big, try a 36B. These sizes have similar cup sizes, but the band will be slightly different.
