Shortening a trousers can be expensive, especially if you have to do it every time you purchase a new pair of trousers. Whether it is men’s or women’s trousers, few of us are a perfect “off-the-rack” size. Shortening your own trousers can be done easily with just basic sewing skills. A second person is helpful to help you mark that first measurement at the hem level, while you have them on.
Measure and mark where you will put the hem, plus an additional 1 inch, around both bottom trouser legs. Cut the excess fabric off.
Sew close to the edge of the zigzag stitch, with matching thread, for casual trousers, such as jeans. For dressier trousers, hand sew the hem on each leg with a slip stitch. Press the new hem with your iron to make a crease.
