Attach the waistband by pinning it to the skirt opening, sewing it in place with a straight stitch, then folding and stitching the top edge closed

A waistband holds a skirt at your body and takes the most stress of any seam you'll sew. The standard method uses a facing—a strip of fabric that wraps around the inside of the waistband to finish the raw edges. You'll pin the waistband to the skirt opening, sew it down, then fold the facing to the inside and stitch it closed. The whole process takes about 30 to 45 minutes once you have the waistband cut and interfaced.

This guide assumes you have already cut your waistband to the correct length (your waist measurement plus 1 inch for seam allowance) and width (usually 2 to 2.5 inches), and that you have already sewn the side seams of your skirt closed. You will also need a needle, thread, pins, scissors, and a sewing machine.

Key Takeaways

  • Press interfacing to the wrong side of the waistband before you attach it, so the waistband stays firm and doesn't roll or twist.
  • Pin the waistband to the skirt opening with right sides together, matching the center front and back, then sew with a 5/8-inch seam allowance.
  • Fold the top edge of the waistband down 5/8 inch and press it, then fold the waistband to the inside of the skirt and pin the folded edge over the seam line.
  • Stitch the folded edge down by hand or machine, sewing as close to the fold as possible so the stitches don't show on the outside of the skirt.
  • The most common mistake is sewing the waistband too tight—measure your waist before you cut, and leave 1 inch for seam allowance and a small amount of ease so the skirt sits comfortably.

Prepare the waistband with interfacing

Before you attach the waistband, you need to stabilize it with interfacing—a layer of fabric fused to the back that keeps the waistband from stretching or rolling. Cut a strip of interfacing the same length as your waistband and about 1 inch wide. Place the interfacing on the wrong side of the waistband, centered so there is 1/2 inch of waistband fabric showing on all sides.

Set your iron to the heat setting recommended on the interfacing package (usually medium to medium-high). Press the interfacing onto the waistband for 10 to 15 seconds, moving the iron slowly from one end to the other. Do not slide the iron back and forth—pressing down and lifting up works better and prevents the interfacing from shifting. Let the waistband cool for a minute before you pick it up.

Once the interfacing is fused, fold the waistband in half lengthwise with wrong sides together and press the fold. This crease marks the center line of the waistband and makes it easier to attach evenly. Open the waistband back up—you should see a crease running down the middle.

Pin the waistband to the skirt opening

Lay your skirt flat on the table with the right side facing up. The waistband will attach to the top edge of the skirt with right sides together, meaning the pretty side of the waistband faces the pretty side of the skirt. Fold the waistband in half lengthwise again (right sides together this time) and pinch the fold to mark the center. Do the same with the skirt—fold it in half at the center front and center back and pinch to mark.

Match the center marks on the waistband and skirt and pin them together. Then match the side seams of the skirt to the ends of the waistband and pin those points. You now have four pins holding the waistband in place at the quarter-points. Smooth the skirt fabric between each pair of pins and add more pins every 2 to 3 inches, keeping the edges even. The waistband should lie flat against the skirt opening with no bunching or puckering.

Check that the waistband ends meet exactly—they should overlap by 5/8 inch (your seam allowance) and no more. If the waistband is too long or too short, remove the pins and trim or add fabric as needed before you sew.

Sew the waistband to the skirt

Set your sewing machine to a straight stitch with a stitch length of 2.5 to 3 millimeters. Thread the machine with thread that matches your skirt fabric. Sew along the pinned edge, starting at one end of the waistband and sewing toward the other. Keep the edge of the presser foot aligned with the 5/8-inch seam allowance mark on the machine bed, or use a seam guide if your machine has one.

Sew slowly and remove pins as you approach them—do not sew over pins, as this can break the needle or damage the machine. When you reach the end of the waistband, backstitch three or four stitches to lock the thread, then cut the thread and remove the skirt from the machine. Press the seam flat with an iron, pressing from the skirt side first, then from the waistband side.

Trim the seam allowance to 1/4 inch using sharp scissors or a rotary cutter. This reduces bulk inside the waistband and makes the next step easier. Be careful not to cut the skirt fabric itself—hold the waistband up and trim only the seam allowance underneath.

Fold and press the waistband facing

The facing is the top edge of the waistband that will fold to the inside of the skirt. Fold the top edge of the waistband down 5/8 inch (the same width as your seam allowance) and press it with an iron. This fold should be crisp and even all the way around the skirt. If the fold is uneven in places, unfold it, adjust the fabric, and press again.

Now fold the entire waistband to the inside of the skirt, using the crease you pressed earlier as your guide. The folded edge of the facing should sit just barely on top of the seam line where the waistband meets the skirt. Pin the facing in place every 2 to 3 inches, making sure the fold is smooth and the waistband sits at the correct height on your body (usually about 1 inch above your natural waist).

Press the waistband again from the inside, using the tip of the iron to press the fold of the facing without creating new creases in the skirt fabric. Let the waistband cool before you remove the pins.

Stitch the facing down by hand or machine

You can finish the waistband by hand or machine. Hand stitching is slower but gives you more control and leaves no visible stitches on the outside of the skirt. Machine stitching is faster but requires a technique called stitch-in-the-ditch, where you sew directly in the seam line so the stitches hide inside the fold.

For hand stitching, thread a needle with thread that matches your skirt. Use a slip stitch—a stitch that runs inside the fold of the facing and catches only a few threads of the skirt fabric underneath. Bring the needle up through the fold, then insert it directly across into the skirt fabric, run it forward about 1/4 inch inside the fabric, and bring it back out through the fold. Repeat this motion all the way around the waistband. The stitches should be about 1/4 inch apart and nearly invisible from the outside.

For machine stitching, set your machine back to a straight stitch and thread it with matching thread. Sew directly in the seam line where the waistband meets the skirt, sewing from the inside of the skirt so you can see the fold of the facing as you work. Sew slowly and keep the needle exactly in the crease—if you drift to the left, you'll sew into the skirt fabric and create a visible line on the outside. Backstitch at the beginning and end to lock the thread.

Finish the waistband ends

The two ends of the waistband overlap by 5/8 inch and need to be sewn together so they don't come apart. Fold the waistband ends so they meet at a right angle to the rest of the waistband, creating a small rectangular pocket. Pin this pocket closed and sew it by hand using a slip stitch, or sew it by machine using a straight stitch. Sew through all layers—the waistband, the facing, and the seam allowance underneath.

Once both ends are sewn, try on the skirt and check that the waistband sits at the right height and feels comfortable. The waistband should be snug enough to hold the skirt up but loose enough that you can fit one finger inside. If the waistband is too tight or too loose, you can adjust it by taking in or letting out the side seams of the skirt, but this requires removing the waistband and starting over.

Common mistakes and how to avoid them

The most common mistake is sewing the waistband too tight. Many sewers measure their waist and cut the waistband to exactly that measurement, forgetting to add ease—a small amount of extra room so the skirt sits comfortably and doesn't restrict movement. Add at least 1/2 inch of ease to your waist measurement before you cut the waistband. If you already cut the waistband too tight, you can let out the side seams of the skirt by 1/4 inch on each side, which adds 1/2 inch to the total waist measurement.

Another common mistake is not pressing the interfacing firmly enough. If the interfacing is not fully fused to the waistband, it will shift when you sew and create wrinkles or puckers. Press for the full time recommended on the interfacing package, and press again after you attach the waistband to make sure the interfacing stays in place.

A third mistake is sewing the facing down too far from the fold. If you sew the facing more than 1/4 inch away from the fold, the stitches will be visible on the outside of the skirt. Sew as close to the fold as possible, whether you're using a slip stitch by hand or a stitch-in-the-ditch by machine.

Frequently Asked Questions

Can I use a waistband that's already finished on one edge?

Yes. Pre-made waistbands with one finished edge are sold at fabric stores and save time. Attach the raw edge to the skirt opening using the same method described above, then fold the finished edge to the inside and stitch it down. You skip the step of pressing the facing edge because it's already finished.

What if my waistband is bunching or puckering after I sew it?

Bunching usually means the waistband is too long for the skirt opening. Remove the waistband, trim 1/4 to 1/2 inch from the length, and sew it back on. Puckering usually means the interfacing shifted during sewing. Press the waistband again with a hot iron to fuse the interfacing back in place, then re-sew the facing if needed.

Do I need to use interfacing in the waistband?

Interfacing is not strictly required, but it makes a big difference in how the waistband looks and feels. Without interfacing, the waistband will stretch, roll, and wrinkle over time. If you skip interfacing, use a heavier fabric for the waistband, such as cotton twill or linen, to give it some body.

Can I sew the waistband on by machine instead of by hand?

Yes. Machine stitching is faster and just as strong as hand stitching. Use the stitch-in-the-ditch method described above, sewing directly in the seam line so the stitches hide inside the fold. Practice on a scrap of fabric first to get the needle placement right.

What thread should I use for the waistband?

Use thread that matches your skirt fabric in color. If you're sewing the facing by hand, use a single strand of thread. If you're sewing by machine, use the same thread in the bobbin and the needle. Polyester thread is durable and works well for most fabrics; cotton thread works for cotton and linen skirts.
