Palazzo-style pants look fantastic on any size body. Their loose breezy style is so comfortable and depending on your fabric - absolutely elegant.

This tutorial doesn’t use a prepared pants sewing pattern. In fact, I’m going to show you how to sew pants without a pattern and it’s not that complicated!

I also made a tutorial on how to make a blouse without a pattern. So, you can use both of these guides to sew a matching set.

Let’s get started on learning how to sew pants together.

Tools and materials:

  • 2-3 yards jersey knit fabric (make sure it’s stretchy enough to pull on and off without needing to insert a zipper)
  • Sewing machine
  • Your own well-fitting palazzo style pants to serve as a template
  • Scissors
  • Measuring tape
How to make pants without a pattern

1. Make the pattern

Fold your fabric in half.

A sustainable tip: to prevent fabric waste, fold both ends of your fabric to meet at the center. 

Lay your own well-fitting palazzo-style pants on top of the folded fabric, folded in half lengthwise so the crotch sticks out. Fold the waistband down inwards.

Carefully cut out the pattern, leaving a ½-inch seam allowance.

Cut open on the fold.

Now lay your pants on the other part of the folded fabric. Make sure to fold the waistband down again.

Cutting out the pants sewing pattern

Cut with ½-inch seam allowance. Cut along the fold.

2. Start sewing

Keep the pieces you cut together. Pin both sides of the pants, leaving the crotch area on both unpinned.

Make sure that the right or good sides of the pants are together inside and the wrong side is on the outside.

Cutting out the waistband

Right after pinning, measure your waist. Fold the fabric and measure 2 ½ inches on the fold and your waist measurement. Cut this piece of fabric and lay aside for now.

Sewing the inseam on pants

Use a zigzag stitch to sew the outside straight seams and the inner seams of both pant legs, remembering to leave the crotch area unsewn.

3. Put the pants together

Turn one pant leg inside out so the right (good) leg is facing you. Place the right side facing out pant leg into the other pant leg. This way both right sides are together.

Match up the crotch seams together and pin in place. Pin all around. Stitch together. Then, turn the pants inside out.

4. Make and attach the waistband

Open the fabric you cut for the waistband. Fold it so the right sides are together. Pin the short end together and sew it with a straight stitch to make a loop. Trim the excess.

Flipping the waistband

Flip the waistband so it’s right side facing out.

Folding the waistband

Fold in half. 

Attaching the waistband to the pants

Slip the pants into the waistband loop. Lay the unfolded edge right at the raw edge. Line up the back center seam with the seam of the waistband. Pin it together.

Then, pin in the center front and both side seams. Stitch the waistband to the pants.

    Remember you have a front and back to pants which are different. You will need to have the two patterns to make the pants fit well in the crotch area.
