Measuring Tips to Assure The Best Fit
With arms at sides, place tape measure under your arms and run it around the fullest part of the chest and across the shoulder blades.
Start the end of the tape on the outside edge of the shoulder. Measure up over the curve of the shoulders and to outside edge of the other shoulder.
Find the natural crease of your waist by bending to one side. Run tape measure around your natural waistline, keeping one finger between the tape and your body for a comfortable fit.
