Measurement tips to ensure the best fit
With the arms on the sides, place the measure under your arms and drive it around most of the bust and over the shoulder blade.
Find the natural folding at the waist by bending to one side. Drive a tape measure around your natural waist, hold a finger between the strap and your body for a comfortable fit.
With your feet together, measure the tape around the largest part of the hips / seat, about 7 to 8 inches below your waist.
For full length pants, run the tape measure along the inside of your leg, from just below the scrap to about 1 inch below the ankle.
