CALCULATE BAND SIZE
Measure around your rib cage just beneath your breasts.
Be sure that the tape is level from front to back and parallel to the floor.
If you're in between sizes, the smaller band will usually offer better support.

Rib Measurement Band Size

29"-32" 34 band

33"-34" 36 band

35"-39" 38 band

39"-41" 40 band

42"-43" 42 band


CALCULATE CUP SIZE
Measure around the bust at the fullest point while wearing an unpadded bra.
Each inch of difference between this measurement and your band size = a cup size.
If your band size is 34 and your bust measurement is 36", you wear a B cup.


If the difference is:

2 inches- B cup

3 inches- C cup

4 inches- D cup

5 inches- DD cup

6 inches- E cup

7 inches- F cup
