How to Hem Dress Slacks?

To hem dress slacks, you’ll need a sharp scissors, pins, measuring tape, tailor’s chalk, and a needle and thread.

First, wear the slacks with the shoes on your feet that you expect to be wearing when finished. Fold the excess material down to the length you want it to reach. Pin in place, then stand up and check yourself in a mirror for proper length.

Measuring down from the floor at several points around each leg, mark the new hemline with tailor’s chalk, ensuring evenness. Use some chalk to join up the marks to create a smooth fold line.

You can either hand-stitch or use the sewing machine; with hand-stitching, you’ll have much more control, and a blind hem stitch on your sewing machine is virtually invisible if sewn correctly.

And there you have it—steps toward a professional alteration look. Now, let’s get into details for a perfectly tailored result.

Supplies Needed

Supplies Needed
To hem your dress slacks like a pro, you’ll need the right tools. Gather a sharp pair of scissors, pins, a measuring tape, and tailor’s chalk for marking.

Choose a needle that suits your fabric and thread that matches perfectly. Decide between hand sewing or using a machine – both work well.

If you have one, a serger can give your hem a polished finish. Don’t forget an iron for crisp folds and a hem gauge for precision.

With these supplies at hand, you’re ready to tackle your pant length like a seasoned tailor.

Pinning the Hem

Pinning the Hem
Next, you’ll get your slacks ready for pinning your hem. Here’s how to prepare:

  1. Wear the slacks with the kind of shoes you’ll usually wear.
  2. Fold up the extra material to your desired length.
  3. Place straight pins directly into the fold and space equally apart.
  4. Walk around to check the length is comfortable.

Once you’ve pinned in the hem, step back to check in a mirror. The length that’s pinned up should hit at the right spot on your shoes and be even. Use safety pins to replace the straight pins, holding the seam in more securely. Keep in mind that proper pinning will yield a professional finish in the hem.

Measuring

Measuring
Now that you’ve pinned the hem, measure precisely. Take your tape measure and measure, checking the hem length at several spots around each leg to ensure that it’s even. Check both sides against one another with matching measurements to ensure hem symmetry.

Try to get a consistent width for the hem as much as possible for durability and aesthetics. Mark 3 spots on the pant: inside seam, outside seam, and center back. Look and adjust so it remains even as you go.

Remember that the best hem ever measured is your way to a polished look. Turn down your hem by the measurements you’re satisfied with and choose a matching thread to go ahead.

Hold one thread and keep an even tension.

Marking the New Hemline

Marking the New Hemline
Now it’s time to mark your new hemline. You can use either chalk or a fabric marker, whichever will show up best on your fabric.

Measure up from the original hem at three points across each leg: inside, center, and outside. Mark both the amount to remove and your hem allowance. For accuracy, match both legs up in order to double-check your measurements.

Using a ruler or hem gauge, connect the marks to create a smooth foldline for a professional finish. Be accurate here, as this will ensure even hems.

If you’re not sure, it’s always better to mark a bit longer – you can trim more later when you hem your dress slacks.

Prepping the Pants

Prepping the Pants
Now, having marked your new hemline, get your pants prepared for the perfect hem. First of all, prepare your pants—serge the raw edges to prevent them from fraying. Use thread that’s as near to your slacks as possible; it should be almost invisible. Ensure that both legs are equal before you start working on the document. For accuracy, baste the hem in place using a contrasting thread. Press the folded edge to a crisp for professional Henrik Vibskov style.

• Use tailor’s chalk to mark pant in 3 locations

Serge raw edges for a neater finish.

  • Select matching thread for invisible stitching

    • Baste hem with contrasting thread for easy removal

  • Press folded edge with iron for crispness

Hand Stitching the Hem

Hand Stitching the Hem
Now it’s time to hand-stitch your hem. Choose a needle size appropriate for your fabric and thread color that matches your slacks perfectly.

Begin by knotting your thread and inserting the needle from the inside of the folded hem. Take small, even stitches about 1/4 inch apart, catching just a few threads of the pants’ fabric. This creates a nearly invisible hem. Keep your stitch length consistent for a professional look.

For those who prefer to hem pants without sewing, fabric tape is an option.

Using a Sewing Machine

Using a Sewing Machine
If you’re comfortable with a sewing machine, it will definitely help speed up the process of hemming. Set up your machine to do a blind hem stitch and set as appropriate for your fabric. Choose a thread color that perfectly matches your slacks.

Use a hem gauge, if you have one, to keep the width of the hem consistent as you sew. Keep in mind what you’re trying to achieve here: pants that hang evenly with no lumpiness in the hem allowance.

Slowly feed the fabric through the machine, keeping your hem length consistent. Take it slow—you will start to make mistakes if you’re rushing.

With practice, you can get professional results—which really go a long way to give you that feeling of being a real tailoring pro!

Final Steps: Finishing the Hem

Final Steps: Finishing the Hem
Now, since you have sewn in your hem, your perfectly altered dress slacks are all set to finish off. Here’s how to achieve a polished look:

  1. Iron with a press cloth to protect fabric at hem.
  2. Clip any visible basting stitches or loose threads.
  3. Make sure that the hem is even on both legs.

If you’re looking for something temporary, this is where hem tape, adhesive strips, and fusible web come in handy. These can even be great additions to that side hustle in hemming pants. Keep in mind that if you’re short on time, even glue stick works for a press-on hem. So remember, practice makes perfect with these skills to hem men’s trousers!

Additional Tips

Additional Tips
Additional Tips to Make Your Hemming Project a Success: Here are some more tips to keep in mind for the success of your hemming project.

• Measure with a hem gauge to ensure accuracy and consistent results.

  • Choose tough thread**, like polyester, to stand the wear and tear.
  • Mark your hemline in three places to get an accurate pattern, then cut.

Practice on scrap fabric until it feels like you’ve mastered the technique before you do the slacks.

Sew and look as you go to achieve an even hem all around. Use matching thread and tailor’s chalk so that, if necessary, some inconspicuous markings may easily be removed. A serger will undoubtedly give your hem that kind of professional finish, but realistically, it really isn’t essential. Keep in mind to be patient; it takes a slight time element, and there you have it—the perfect, tailor-made finish you’re looking for.
