The Art of the Tailored Hem
A proper hem is the difference between looking put-together and looking like you tried. Whether you're taking up trousers or finishing a new purchase, here's exactly how to get it right.
5 min read · IrisA hem is not decoration—it's the foundation of fit. Whether your pants pool at your ankles or your midi skirt grazes the wrong part of your leg, the hem determines how intentional your entire outfit reads. The good news: hemming is learnable, and knowing when to do it yourself versus when to hand it off to a professional will save you money and frustration.
This guide walks you through the anatomy of a hem, the tools you'll need, and the exact techniques that separate a sloppy fold from a crisp, tailored finish. You'll also learn to read your garment and decide whether needle and thread or a professional tailor is the right move.
The hem is where intention meets fabric. Get it right, and everything else falls into place.
Step one · 3 minutes
Measure twice, cut never
Put on the garment with the shoes you'll actually wear it with—this matters more than you think. Have someone mark where the hem should fall using tailor's chalk or a fabric pencil, or do it yourself in front of a mirror. For trousers, the hem should just graze the top of your shoe; for skirts and dresses, measure from the floor up to your desired length. Mark all the way around the garment, not just one spot. Take the garment off and measure the distance from the current hem to your mark. Write this number down.
Heel height changes everything. A hem that works with flats will be too short in heels. Measure for your most-worn shoe situation.

Decide: DIY or tailor
Hand-stitching a hem takes patience but is absolutely doable for straight hems on woven fabrics like cotton and wool. Skip the DIY route if you're working with stretchy knits, delicate silks, or curved hems (like on A-line skirts). A professional tailor costs $15–$40 per garment and is worth it for anything precious or technically complex. For basic trouser and straight skirt hems, you can confidently go the needle route.
If you're hemming more than three items, batch them and take them to a tailor. Your time is worth something.

Fold, press, and pin
Turn the garment inside out and fold the hem up to your marked line. Press this fold with an iron on the appropriate heat setting for your fabric—steam helps set the crease. Once cool, fold the raw edge up another half-inch (or to your marked line if you're using a hem tape) and press again. This creates a clean, finished edge. Pin every inch or so around the entire hem, keeping pins perpendicular to the fold. The pins hold everything in place while you stitch.
A pressing ham (a tailor's tool shaped like a ham) helps you press curved hems evenly. A rolled-up towel works in a pinch.

Stitch with the slip stitch
Thread your needle and knot the end. Slide the needle into the fold of the hem so the knot is hidden inside the fold. Bring the needle out and take a tiny stitch (about 1/8 inch) in the garment fabric directly above the hem fold. Immediately bring the needle back into the fold and slide it along inside the fold for about 1/4 inch. Come back out and repeat. The magic is that your stitches are almost invisible from the outside because they're hidden in the fold and the garment fabric. Keep your stitches small and consistent. Work your way around the entire hem.
Use thread that matches your fabric, not your skin tone. A single thread (not doubled) is easier to control and creates a less visible stitch.
Step five · 3 minutes
Secure and press
When you reach the end, make a small knot by looping your thread and pulling it tight, then take one final stitch through the knot to anchor it. Trim the thread. Remove all pins. Turn the garment right-side out and try it on to check the length and hang. Press the hem one final time from the outside using a pressing cloth (a thin cotton cloth between the iron and fabric prevents shine marks). Let it cool completely before wearing.
A pressing cloth is essential for dark fabrics. Even a clean cotton handkerchief works.

Know when to use hem tape
Fusible hem tape (also called hem tape or bonding tape) is a no-sew alternative that uses heat to adhere the hem. It works best on sturdy woven fabrics and is genuinely useful for quick fixes. Cut a strip of tape to fit inside your folded hem, place it between the two layers, and press with a hot iron for 10–15 seconds. It's not as durable as hand-stitching for everyday wear, but it's perfect for temporary hems or delicate fabrics you don't want to puncture with a needle.
Test hem tape on a scrap of your fabric first. Some synthetics don't respond well to the heat, and the tape can sometimes show through light fabrics.
How to know your hem is tailored
A professional hem is invisible from the outside, hangs evenly all the way around, and doesn't pull or pucker. The garment should move naturally without the hem catching or bunching. When you wear it, you should forget the hem exists—that's the goal.
Questions at the mirror.
My stitches are too visible. What went wrong?
Your stitches were too large or your thread color didn't match. Rip out the hem carefully using a seam ripper, and try again with smaller stitches (aim for 1/8 inch) and thread that matches your fabric exactly.
The hem puckers even though I pressed it. How do I fix it?
Puckering usually means you pulled your thread too tight while stitching. Rip it out and redo it with a looser hand—the thread should be snug but not taut.
Can I hem stretchy fabrics like jersey or knits?
Hand-stitching stretchy fabrics is difficult because the stitches can snap. Use a professional tailor or try a ballpoint needle with hem tape for a temporary fix. A sewing machine with a stretch stitch is ideal if you have access to one.
How long does a hand-stitched hem last?
A properly executed slip stitch should last through many wears and washes if you're gentle. If a stitch comes loose, you can easily re-stitch just that section rather than redoing the entire hem.
