Hook & Loop side closures allow the user to adjust the sizing and to completely open the garment flat to make dressing easier. To determine the correct size, measure the waist and hip and choose the larger size. If the measurements are at the higher end of a size range, don’t go to a larger size. To measure rise, begin about 1 inch below the belly button, measure down through the legs, and up to the position on the back that matches the starting position on the front.
