Resizing the waist of jeans is a common alteration that can be done at home with a few simple steps. There are several methods to make the waist of jeans smaller, including sewing darts, taking in the side seams, or using a waist cincher. Choosing the best method will depend on the amount of reduction needed and the style of the jeans.
One common method for making the waist of jeans smaller is to sew darts in the back of the waistband. This method is relatively simple and can be done by hand or machine. To sew darts, start by marking the center of the waistband and measuring the desired amount of reduction on each side. Pin and sew darts on both sides of the center mark, tapering the darts to a point at the waistband seam. Trim any excess fabric and press the darts flat.
