Butterick 4686 uses the same pattern piece for the front and the back. I know my front is way different than my back so I am going to create a front and a back pattern and move the zipper to the center back.
So here is what I am going to do starting with the original pattern. I numbered the pleats to help in the example.
I will remove 3 of the pleats by folding out the pleats numbered 2, 4, and 6 (fold out completely). This will remove some of the volume at the pleat release to the hemline.
Retrace and then use this as my front pattern piece.
For the back I will draw a line down the center to create the new center back seam line.
Then add seam allowance and mark the zipper placement.
Taking the new pattern pieces for the pleated skirt folding the pleats and pin using McCall 3830 as a guide for fit in the waist and hip area. I will alter using the pleats and side seams if need be.
