How to Let Out a Waistband on Jeans

Basic Sewing Supplies Needed

Step 1: Making the Cut

I measured my waist to determine exactly how much additional fabric I needed. In this case it was a little under 2″ – which means approximately 1″ at each side seam.

At the side seams I cut down to the bottom of the back yoke. I did this because pants that are snug in the waist (on me) are usually a little snug through he tummy, too.

Step 2: Make Insert

These were pants I had previously made, so I had matching fabric on hand. However, if you are altering a pair of jeans you own, pop into your local fabric store and pick up a small piece of denim to use as your expansion fabric.

Fold the denim in half and be sure it is long enough to fill the opening.

Step 3: Mark the Insert

I used a water soluble fabric marker, but any fabric marker would work. Mark the opening onto the expansion fabric. Repeat on the other side.

Step 4: Finish Insert Edges

Cut down the size of the expansion fabric and finish the raw edges. I used my serger, but folding it under and top stitching works, too. What you want are clean edges. Make one of these for each side of your jeans.

Step 5: Pin Insert to Waistband

Your marking lines should still be visible. Line up the side seam opening with expansion fabric markings. Pin in place to hold.

Step 6: Stitch Down Insert

Zigzag stitch the two pieces of fabric together. I increased the width of my zigzag and lowered the stitch number. It’s almost like an appliqué stitch ~ very dense. Repeat on the other side.

Step 7: Finished!

That’s all there is to it. How easy is that. I wear these jeans (actually capris) with a loose peasant-style top, so the side seam expansion never shows.

This is a very fast alteration that almost anyone can accomplish. There are ways to make the expansion a little more fancy, but I thought I’d show you a quick way to Let Out the Waistband on a pair of jeans that may otherwise have been sent to the thrift shop.

One word of caution, it is easy to ‘over-size’ your waist here. When your expansion pieces are pinned in place, it is a good idea to machine baste them and then wear the pants for a few minutes. You wouldn’t want to have to rip this out those zigzag stitches because the waist is now too big.
