To measure accurately, keep the tape parallel to the floor, only undergarments and do not measure over the clothing.
Place the measuring tape under your arms and run it around the fullest part of the bust line and across the shoulder blades.
Run the measuring tape around your natural waistline at the crease. Keep a finger’s distance between the tape and your body for a comfortable fit.
With your feet together, wrap the measuring tape around the fullest part of your hips/seat – around 8 to 9 inches below your waistline.
