Still I liked this dress/skirt so much I made another one:
You’ll need a nice stretchy knit. It is ideal if it can stretch well against the grain and with the grain. If you do, you can get less fabric because you can use the width of the fabric and not just the length. You want a piece just a bit wider than your hips and as long as your hips to the floor plus about 20 inches.I got 1 1/8 a yd. of the green 58 in. wide knit and it worked great.
