How to Measure:: For best results, have someone take the measurement for you.
Torso:: Start at the iliac crest (the top of your hipbone that you can feel like a shelf on the side of your body). From this level on your spine, measure to the C7 vertebrae, the knobby bone at the base of your neck when you put your head down. Make sure to keep your back straight while having the measurement taken.
Hip:: Measure around your hips, at your iliac crest, not your waist.
