1. The first thing I did was draw the straight grainline since I don't cut my waistband on the bias.
2. Align the waistband and bake yoke pieces at the center back. 2" from the center back, draw a vertical line from the top of the waistband to the bottom of the yoke. Draw two or three more vertical lines 2 inches apart from the first one. The number of lines you draw depends on the amount of width you plan to remove from the waistband.
I just had a revelation about this method for this particular waistband! I'll share it at the end of the post.
3. I removed 4 inches of width altogether. I drew four vertical lines and will dart out 1/2" at each line. To do this, mark 1/4" on either side of each vertical line. Since I worked with one-half of the waistband, the amount removed on this piece is 2 inches.

5. Finally, fold on the vertical line, overlap the dart edges, and tape in place. Alternatively, you can cut on one dart leg, match it with the other, and tape in place. Do the same for the yoke piece. The changes to the yoke piece are so small, I didn't bother taking out the excess. I haven't had a problem with fitting the waistband to the yoke.
As I was writing this post, thought more about how this method affects this particular waistband. The Jalie waistband is designed to be cut into two pieces, sewn ad the center back, and then joined to the pants front/back. Then, it's folded lengthwise and topstitched. So actually, the waist seam is in the center of the piece.
So the amount removed is actually less than planned since the dart isn't as wide in this area. I never realized this until now. This may explain why my waistband still gapes a bit. I will have to address this in future pairs of jeans.
I hope this was helpful!
