How to Turn Old Jeans into a Chic Denim Skirt

Have a pair of beloved jeans where the knees have blown out, or weight changes have made them fit a bit awkwardly around your calves? Don’t toss them into the donation pile just yet. Transforming them into an effortless denim skirt is one of the most satisfying, eco-friendly DIY projects you can tackle at home.

While almost any pair of pants can technically become a skirt, denim is the undisputed champion of upcycling. Its sturdy weave holds up beautifully to alterations, hides beginner sewing mistakes, and yields a casual silhouette that never goes out of style. Here is how to make your own custom denim skirt in just a few straightforward steps.

What You Will Need

• A pair of old jeans (that still fit comfortably in the waist and hips)
• Sewing machine equipped with a heavy-duty denim needle
• Matching denim thread (or contrasting gold/tan topstitching thread)
• Fabric scissors
• Seam ripper
• Sewing pins

Step-by-Step Guide to Crafting Your Skirt

1. Pick jeans that fit your waist and hips comfortably. Avoid using jeans that are multiple sizes too big or small in hopes of doing a complete overhaul. Resizing the waistband and seat adds complex tailoring that requires professional expertise. Instead, choose a pair—skinny, straight, or boyfriend cut—that already sits comfortably around your hips and waist.

2. Cut to an intentional starting length. Denim usually wears thin at the knees and thighs first. Lay your jeans on a flat surface and use fabric scissors to cut straight across at knee level. Always err on the longer side—you can easily trim the hem higher once the skirt is formed, but you cannot undo a cut that is too short.

3. Unpick the inner leg seams. Take your seam ripper and carefully undo the entire inseam running along the inside of both legs, going all the way up through the crotch curve. Work patiently so you don’t rip or puncture the denim fabric itself. Leave the outer side seams untouched.

4. Turn the jeans inside out and prep the panels. Flip your opened jeans inside out. Lay the front panels flat so that the inner edges overlap naturally where the legs used to split. Pin them securely in a straight line down the center. Repeat this step for the back panels, smoothing out any bunching around the seat area.

5. Sew the seams on your machine. Using your sewing machine, stitch down the pinned center lines to join the leg openings into a cohesive skirt. Once the structural seam is finished, turn the skirt right side out and press it flat. Adding a neat topstitch along the outside of the center seam creates that classic, store-bought denim aesthetic. (Note: Denim is far too dense and thick to sew effectively by hand—a sewing machine is essential for seams that will actually hold up to everyday wear.)

6. Customize and embellish. Now comes the fun part! While your creative station is set up, give your skirt personal character. You can fray the bottom hem with a pair of tweezers for a relaxed raw-edge look, apply vintage patches, distress the pockets with sandpaper, or stitch on decorative buttons.

7. Style your new favorite piece. Just like that, your unworn jeans have transformed into a versatile wardrobe staple. Whether you pair it with a crisp white tee and sneakers in the summer or layer it over tights with boots in the fall, you’ll love having a one-of-a-kind upcycled piece made entirely by you.
