Measuring Instructions

  1. Take your measurements using a cloth measuring tape and write them down. Have someone measure you if possible, otherwise you can measure yourself.

    Chest: the largest circumference around your chest - usually around nipple line. Measuree should lift arms out to side, place tape around chest, then lower arms to side. Make sure tape stays level around the back.

    Waist: the smallest circumference between your chest and buttocks; not where you would measure the waist for a pair of pants, but normally a couple of inches higher, just below the base of the rib cage. If your waist is larger than chest or buttocks, take largest circumference of waist area.

    Hips: The widest circumference of your lower hips. Be sure to keep the measuring tape level.

  2. Find your size on the chart starting with the Chest, then find the best size matching your Height, Waist and Hips
