Measure around the fullest part of your bust, keeping the tape parallel to the floor. Keep the tape comfortably loose.
Measure around your natural waistline, which is typically the narrowest part of your torso, about an inch above your belly button.
Measure around the fullest part of your hips, keeping the tape parallel to the floor. Stand with your feet together.
For the most accurate measurements, use a soft measuring tape and measure over bare skin or lightweight clothing. Don't pull the tape too tight—it should rest comfortably against your body.
