How to take in pants

1. Take in the pants at the waist

These pants are super big on me, so the first step is taking them in. Simply wear your pants, pinch the sides, mark the excess fabric, and pin those marks. 

Seam ripping pants at the waistband

Starting at the waist, seam rip all of the sides of the waistband. Make sure to seam rip both layers of fabric. 

Re-pinning the seams to take in the pants

Now, take your outside seams, match the pins together, repin in place, and sew to secure.

2. Take in the pants at the thigh

Also, my thigh area needed to be taken in, so I did the same method as I did above. 

Cutting off the excess fabric

Cut off the excess fabric from the outer waist seam. 

Hiding the raw edges

If you have an inner lining, fold it in toward the outer one so that you hide all the raw edges. 

Sewing the tuxedo pants waistband

Repeat this on both sides and then sew the top and bottom of the waistband. 

Hand-stitching the raw edges

I hand-stitched the rest of the raw edge by joining the inner seam to the outer layer, too.

This is what you should end up with. 

Taking in the tuxedo pant legs

3. Take in the pant legs

Since the pants are wide-legged, I wore them again and marked with chalk where I'd like to take them in at the bottom. 

Cutting the excess fabric off the pant legs

After sewing the leg sections to your liking, cut out the excess fabric on both sides. 

Sewing a zigzag stitch along the raw edges

Then, use a zigzag stitch on the new raw edges; this will prevent the fabric from fraying. 


Tip: You can also use a serger for this. 

Marking the new pants length with chalk

4. Adjust the length

I wanted these pants to be ankle length, so I folded the bottoms up until I got to my desired length. Then, I marked this length with chalk. 

Pinning the new pant leg hems

Put pins at the chalk marks and cut off the original hem. 

Double-folding the pant legs to sew

Double fold the pants (upward). Make sure the raw edge touches the pin on the first fold. Then, fold up again. 

Pinning the new hems

Pin all around to secure. Ensure that the double fold is symmetrical. 

Opening the side seams flat

Also, when folding, make sure to open the side seams flat before. 

Sewing the very top of the fold

Stitch the very top of the fold once both legs are folded and pinned. 

Tearing strips from denim fabric

5. Add the tuxedo stripe

I'm going to be adding a denim tuxedo stripe to these pants for a bit of flair and edge. First, start by tearing two strips from your denim fabric. By tearing them, it will encourage the edges to fray. 

Make your own tuxedo pants

Pin these strips to the outer seams of the pants, leaving a tail hanging off the end. 

Folding the strip end into the waistband

When you get to the top, fold the end of the strip to the inside of the waistband. 

Sewing the tuxedo stripe to the pant leg

Next, stitch these down on each edge and leave a bit of room for the denim to fray even more. 

Using fusible webbing for the bottom

Stitching the strips down on my sewing machine proved to be a little difficult as I got to the bottom of the legs. So, I took matters into my own hands and hand sewed the rest.


Then, I realized it would take super long to stitch manually so I went for the next best thing; fusible webbing. Let me tell you, this stuff saves lives! 

Adhering the stripe with fusible webbing

Put a couple of strips under where your denim strip will lay.

Ironing the fusible webbing

Lay your denim on top and press your iron (with steam) right on top so that the strip adheres.
