Making pants smaller at the waist is a common alteration that can be done at home with a sewing machine or by hand. There are a few different ways to do this, depending on the type of pants and the amount of fabric you need to remove.
One method is to take in the side seams of the pants. This is a good option if you need to remove a small amount of fabric, and it will not affect the overall fit of the pants. To do this, simply sew a new seam along the inside of the side seam, starting from the waistband and working your way down to the hem. Be sure to leave a small opening at the bottom of the seam so that you can turn the pants right side out.
