In this tutorial, we are going to show you how to enlarge jeans at the waist. You can use this fix to enlarge the hips as well if you need to.
Here I have a pair of jeans that I need to upsize at the waist area. I’ve been using different ways to do it, including adding a denim piece at the center back seam or at the side seams. But I’ve found out that adding elastic is actually the way that works best for a couple of reasons.
First, the elastic stretches. This is useful when you are not sure exactly how much to add to the waistband or the size of the waist changes. Second, black elastic looks somewhat like a decorative element.
While denim fabric pieces could never exactly match the color of the jeans. Therefore, it’s easy to tell that the jeans have been altered. So for quite some time now, this is the way we prefer to enlarge the waist on jeans for our clients.
But, if you would rather use denim to enlarge the waist, you can still follow the steps described here.
Here are the written instructions. You are going to find the video tutorial at the bottom of this post.
To enlarge the jeans at the waist, unpick a bit of the side seams and cut through the waistband
First, we need to detach the waistband from the side seam area so that we can release the side seam stitches. Remove just enough of the stitches so that you are able to release the side seam. You don’t want to break a lot of the stitching here because otherwise you will have to restore it at the end.
Here I have to break two horizontal stitches to release the side seam (image 1).
