Choosing the right cup size is crucial for achieving optimum support.

The best way to determine the right cup size is by taking a few measurements while wearing a well-fitting bra. First measure around the fullest part of your bust (1) and then measure around your ribcage just below the breasts (2). By calculating the difference in cm between the bust measurement (1) and the ribcage measurement (2), you can then determine your cup size.

Bust measurement (1) ?
Ribcage measurement (2) = Cup size
          7 - 10 cm          A
       10 - 13 cm           B
       13 - 16 cm           C
       16 - 19 cm           D
       19 - 22 cm           E

For example:
Bust measurement: 90 cm
Ribcage measurement: 75 cm
Difference: 15 cm = cup size 75 C
