A: Measure your underbust (directly under your breasts) using a tape measure, making sure the tape is parallel with the ground. It should not be loose or binding, just nicely snug. Look in the mirror to assure the measuring tape is parallel to the floor. The placement of the measuring tape is important – you want to measure where the bra band will sit.
B: Find your number in inches and select it from the dropdown menu above. Be sure to round all fractional measurements to the nearest whole number. Round to the nearest inch. For example, if your measurement is 33 3/8″, round down to 33″. If your measurement is 35 1/2″ or more, round up to 36″.
