My take is that of a classic pleated skirt. The fabric I used is tartan (the black watch tartan to be specific) which gives it a preppy, schoolgirlish feel, but it would work well too in a different fabric.

You will need:
-fabric, aprox 2 meters
-matching thread
-interfacing
-a zipper
-a sewing machine
-an iron
-pins
