For your waist measurement, please take a tape measure and place it around your waist, going over your belly button. The tape should not be too tight or too loose, tighten it firmly and see the number determined by the tape. That will be your waist measurement.
And for your hips measurement, take the tape measure and place it around your hips (in its most prominent part). The tape should not be too loose or too tight. The number that determines the tape is the number of your hip measurement.
