Only cut the inner layer of the waistband. Pinch the inner layer of the waistband and make a small cut using fabric scissors. Do not cut any closer than 0. 5 centimeters from the edges of the waistband. You do not want to accidentally cut the edge of the band.
To avoid pulling the elastic all the way through the waistband and out the other side, you can pin the end of the elastic to the waist band.
Make sure that you sew over the elastic in order to secure it in place. Sew both of the holes closed. Use a thicker needle if you are working with denim or any other thick fabric.

The length of elastic will vary depending on the size of your waistband. For example, the elastic should reach about half way between the center belt loop and the side belt loop of your pants.
Then repeat the sewing process, starting on the other side of the center belt loop and sew outwards towards the other side of the elastic. Remove the pins as you are sewing. Do not sew over a pin because this could break your needle. Use a thread that matches the color of the pants.
Choose a belt that matches with your overall look.
