Sizes are a guide. We recommend trying on for the perfect fit.

Bust

Wrap the tape around the fullest part of your chest. Keep it level and comfortably snug — not tight.

Underbust

Measure directly under your breasts, around your ribcage. Exhale, then take the measurement snug but not tight.

Tip

Measure without wearing a bra, or wear a non-padded one. Stand straight with arms at your sides.
