Wearing a non-padded, non-minimizing everyday bra, measure just above the bust by bringing a soft measuring tape across your back at band level, under each arm (elbows down), then around the front to snugly but comfortably line up with where your bra straps meet your cups.
TIP: Odd number or on the half inch? Round down to the nearest even number.
TIP: Did you measure yourself below the bust instead? Follow our guidelines for above-the-bust measuring before entering your Band Size into the Perfect Fit Calculator.
