Band Cinctures: Band cinctures are usually worn over a cassock which is worn over street clothing, including pants and a belt, making it very important to add extra inches beyond a normal belt size. Measure around the stomach where the cincture will be worn, over street clothing. Add 4" to this measurement. Use this total measurement to determine your band cincture size.
