To calculate your bra size, you will need a soft measuring tape, and for best results, either remove your bra or wear the bra that fits you best. Measure directly underneath your breasts on the rib cage, making sure to keep the tape level all the way around your torso.

The tape should feel snug, but not constricting. Enter this as your Band Measurement. Next, measure around the fullest part of your breasts to find your Bust Measurement.
