Start by standing in front of a mirror wearing your best-fitting, non-padded underwire bra. You'll also need a soft measuring tape. Remember to measure in inches.
Band size: measure around your ribcage right under your bust, not too loose or tight, and round up to the nearest inch.
Cup size: following along the breast, measure from the nipple down to the band (under your bust).
Bust: measure under your arms at the fuller part of your bust. Keep tape level across your shoulder blades.
Natural waist: measure around your natural waistline, keeping the tape comfortably loose.
Hips: stand with your feet together and measure around the fullest part of your hips.
Band size: measure in inches around your ribcage right under your bust, not too loose or tight, and round up to the nearest inch.
Bust: measure under your arms at the fuller part of your bust. Keep tape level across your shoulder blades.
