Step-by-Step Bra Measurement

1

Measure Your Band (Underbust)

Ribcage measurement

Wrap a measuring tape directly underneath your breasts, around your ribcage. Keep it snug and level across your back.

27-29" = Size 32 | 29-31" = Size 34 | 31-33" = Size 36 | 33-35" = Size 38 | 35-37" = Size 40
2

Measure Your Bust (Overbust)

Fullest part calculation

Measure loosely around the fullest part of your bust while wearing an unpadded bra. Subtract your Band size from this measurement.

1" Diff = A Cup | 2" Diff = B Cup | 3" Diff = C Cup | 4" Diff = D Cup | 5" Diff = DD Cup
