How to Measure

Measurement figure

Underbust (Band)

Wrap a measuring tape directly under your bust, where the band of your bra sits. Keep the tape snug and parallel to the floor. Exhale to get the smallest measurement.

Bust (Fullest Point)

Measure around the fullest part of your bust, with the tape parallel to the floor and just relaxed against your body — not tight.

Cup Size

Subtract your underbust from your bust measurement (in inches). The difference gives your cup size: 1" = A, 2" = B, 3" = C, 4" = D, 5" = DD/E.

Tip

For best fit, measure without a bra or in a non-padded bra. Round up to the nearest whole inch.
