How to Measure for Underwear
1
Measure your waist
Wrap a soft measuring tape around your natural waistline, the narrowest part of your torso about an inch above your belly button. Keep the tape level and snug but not tight.
2
Measure your hips
Wrap the tape around the fullest part of your hips and buttocks. Stand with your feet together and keep the tape parallel to the floor. Don't pull too tight.
