How to measure
Chest: Measure around the fullest part of your chest, making sure the measuring tape is parallel to the floor and is neither too tight nor too loose.
Waist: Measure around the narrowest part of your waist, usually just above your belly button. Make sure the measuring tape is snug, but not too tight or too loose.
Hips: Measure around the fullest part of your hips, usually around the widest part of your buttocks. Make sure the measuring tape is parallel to the floor and is neither too tight nor too loose.
