Measuring Put the jeans on. Pinch the center back of the waist to pinch in excess. Measure from the right back belt loop to the left back belt loop.
Behind the right back belt loop, use a seam ripper to cut a hole through the inside waistband only. Leave a 1/4-inch gap above and below the hole. Do not cut through the outer waistband.
