The circumference of your chest, across the nipples, at its fullest point. Remember there's a link to an instructional video above!
Bend to your side, allowing your mid-section to crease, place the tape measure in your natural crease; measure the circumference around this point. For many, this is the smallest part of their midsection.
Place the tape measure around the fullest part of your bottom.
Measure the distance from your full hip point (fullest part of your bottom) down to the floor (without shoes).
