How to sew a skirt with ruffles and a zipper in the side seam

My daughter wanted a fluffy school skirt and the other day I made her such a skirt with ruffles and a zipper in the side seam.
The skirt uses about 1.4 m of costume fabric and is 150 cm wide. Consumption is also shown on the pattern page.
