I tried the skirt on and marked where I wanted the top of the waist line to be. I then unzipped it, cut off the top of the dress, and I trimmed the top saving it to be used as a facing for the raised waist. I stitched the facing to enclose the raw edge which would be the bottom of edge of the skirt facing.
I then interfaced the facing. I stitched the top of zipper so that when I zipped the skirt up the zipper tab would not come off, since I had shortened the zipper when I cut off the top of the dress. Next, I attached the facing to the skirt, taking care with the zipper at the top.
I pressed the facing over to the inside of the skirt, topstitched it into place, and then tacked it down at the seams. Now, my $8 skirt was complete. I really love it. I think I will try this strategy again. How else can you get a lovely fitted skirt in less than 2 hours for $8?
