To measure your bust, waist, and hips accurately, use a flexible measuring tape. For the bust, measure around the fullest part of your chest. For the waist, measure around the narrowest part of your torso. For the hips, measure around the fullest part of your hips. The length measurement is taken from the highest point of the shoulder down to the desired hemline. It is advisable to round up to the nearest centimeter for a more comfortable fit.
