How to Tailor Jeans Without Losing the Original Hem

The original hem is what separates a well-made pair from a hastily finished one. Here's how to shorten jeans while keeping that coveted selvage or factory edge intact.

Most people take their jeans to a tailor and accept whatever comes back. But if you've invested in a quality pair—raw denim, vintage finds, or anything with a distinctive original hem—you know that factory finish matters. It's part of the garment's DNA. The good news: you can shorten jeans while keeping that hem entirely intact.

This technique requires patience rather than skill. You're essentially working backward from the bottom, removing inseam fabric instead of cutting from the leg opening. It takes longer than a standard hem, but the result is a pair of jeans that looks untouched.

The original hem is what separates a well-made pair from a hastily finished one.

Step one · 1 minute

Try on and mark your desired length

Put on the jeans with the shoes you'll wear them with most often. Have someone mark the ideal inseam length with a fabric pen or tailor's chalk on the inside of the leg. Mark both legs at the same height from the ground. Take the jeans off and measure from the crotch seam to your mark on each leg—this is your target inseam length.

Mark on the inside leg seam, never on the visible exterior.

Measure the current inseam

Turn the jeans inside out. Measure from the crotch seam down to the original hem on both legs. Write down these measurements. The difference between your target length and the current length is how much fabric you need to remove from the inseam. If your current inseam is 32 inches and you need 30 inches, you're removing 2 inches total.

Measure twice. Cutting is permanent.

Open the inseam carefully

Using a seam ripper, carefully cut and remove the stitches holding the inseam together. Work slowly, especially near the hem—you want to preserve every thread of that original edge. Start from the top of the inseam and work downward. Once the stitches are removed, gently pull the two fabric panels apart. The original hem should remain completely untouched at the bottom.

A seam ripper is sharper and more controlled than scissors. Take your time here.

Trim the inseam panels evenly

Lay each leg flat with the inseam open. Measure down from the original hem by the amount you calculated in step two. Draw a straight line across both inseam panels at this measurement point using a ruler and fabric pen. Cut along this line, removing the excess fabric. You're now left with two separate panels that will reattach at a higher point, shortening the overall inseam while the hem stays put.

Use a rotary cutter and ruler for the straightest cut, or carefully use sharp fabric scissors.

Reattach the inseam with a sewing machine

Thread your sewing machine with thread that matches the original inseam color (usually a dark navy or black). Align the two inseam panels with right sides facing each other, matching the raw edges. Sew a straight seam down the length of the inseam using a standard stitch length. Backstitch at the beginning and end. Press the seam flat with an iron. The original hem remains completely unchanged at the bottom of the leg.

If you're nervous about machine sewing, a hand-stitched whip stitch works too—it just takes longer.

How to know it works.

When you flip the jeans right-side out, the original hem should look identical to how it started. There should be no visible stitching at the hem line, and the selvage or factory edge should be completely intact. The inseam will be slightly higher, but that's hidden inside the leg.

Questions at the mirror.

What if I accidentally cut into the original hem?

If you've nicked the hem edge, you can still salvage it by hand-stitching a small repair using thread that matches the original hem color. A tiny stitch or two is barely noticeable on denim. If the damage is extensive, you may need to accept a traditional hem on this pair.

Can I do this on stretch denim or other fabric blends?

Yes, but be extra careful when opening the inseam. Stretch fabrics can fray more easily. Use a seam ripper rather than scissors, and consider using a stretch stitch on your sewing machine when reattaching the inseam to prevent the seam from snapping later.

Is it worth doing this myself or should I pay a tailor?

If your jeans are high-quality or vintage, a tailor who specializes in denim will charge $25–$45 for this technique. If you're comfortable with basic sewing, the DIY route is free and gives you control over the process. Either way, it's worth the effort for jeans you love.
