With right side up, place the zip under the right-hand folded edge; this should be set back with the zip 2.5cm above the waistband edge. Using a zipper foot, stitch the zip close to the pressed edge. Tack the folded edge on the left side so it’s in line with the seam and covering the zip.

Tack the zip tape onto the loose zip facing on the inside. Stitch close to the teeth using a zip foot, catching the zip and facing only. On the outside, tack the zip facing onto the left slightly beyond the teeth, then stitch in place. There should be a curve below the bottom of the zip. Bring the notches together at the front to make pleats.
