How to Measure
With no shoes on, stand with your back against a wall and your feet together. Measure from the floor to the top of your head.
While standing upright, measure the distance between your waist (typically at navel or top of the hip bone level) and the top of your shoulder, to the left or right of your spine.
Measure around your natural waistline, around the top of the hip bones, inline with the navel while keeping the measuring tape parallel to the ground.
