I chose this particular skirt to start with because it had no lining and no waistband, so it was pretty straightforward sewing. I took 1 inch off each side, and the result looked absolutely perfect; I even managed to keep the stripes evenly matched.
This took me about an hour, but that included trouble shooting the iron, so . . . a really complicated alteration would probably send me Ebay haunting, but for these simple pencil skirts, it's probably worth the effort. Yeah! now I have 3 skirts I can wear that fit.
