Measure around the fullest part of your bust while standing naturally. Keep the tape loose enough to not compress breast tissue.

Pro Tip: This is the first of three measurements we'll use to determine your cup size accurately.

Bend forward at 90 degrees and measure around the fullest part of your hanging breasts.

Pro Tip: This measurement helps account for breast shape and tissue distribution.

Step 4

Lie flat on your back and measure across your breasts at their fullest point.
