- Chalk or Fabric Marker
- Iron
- Pins or Clips

How to Measure and Mark Dress Pants for Accurate Hemming
Measuring with Shoes for the Perfect Break
- Put on the shoes you plan to wear with the pants.
- Wear the dress pants and stand straight.
- Ask a friend to help fold the hem up until the length is right. The pants should fall as you like (touching the top of your shoe for a classic break, for example).
- Mark the spot with chalk or a fabric marker.
Marking Hems Evenly on Both Legs
- Lay the pants flat on a table and smooth out wrinkles.
- Use a ruler or measuring tape to check that both hems are equal from the crotch seam down.
- Mark the hem line all around each pant leg for evenness.
Accurate marking is key to getting symmetrical, professional-looking hems on dress pants.
Step-by-Step Guide: How to Hem Dress Pants
Preparing the Pants: Cutting, Folding, and Pressing
- Remove the original hem with scissors or a seam ripper if necessary.
- Mark the new hemline.
- Trim excess fabric, leaving 2–3 cm (about 1 inch) below the marked line for the hem allowance.
- Fold the raw edge to the inside along the marked line and press with an iron.
- Fold and press a second time for a clean finish.
- Secure with pins or clips.
Hand-Sewing a Blind Hem for Dress Pants
- Thread a needle with matching thread.
- Knot the thread and hide the knot inside the hem fold.
- Pick up one or two threads of the pant fabric, then insert the needle into the hem fold for 1 cm.
- Repeat this stitch, making tiny, nearly invisible stitches along the hem.
- Finish by knotting the thread and trimming the tail.
Using a Sewing Machine for a Professional Blind Hem
- Set your sewing machine to the blind hem stitch.
- Position the folded hem as needed under the presser foot.
- Sew carefully, guiding the fabric for even stitches.
- Check for invisible stitches on the outside of the pant leg.
- Press the hem again for a crisp finish.
Quick No-Sew Hemming Techniques (Hem Tape, Fabric Glue)
- Cut hem tape or apply fabric glue along the inside hem fold.
- Press with an iron (follow tape or glue instructions).
- Let glue dry as directed or allow tape to cool before wearing.
No-sew methods are best for quick fixes or when you do not have sewing tools.
