Then I chopped off the top 4 inches and had a new skirt.
Then I remembered that tight, horizontal stripes are not for the pear-shaped (hence the long sweater). But for those of you narrow-hipped ladies who probably have not yet given birth, go for it!
P.s. If you don't happen to have a stretchy dress lying around, you could easily make this by tracing a pencil skirt you already have onto 2 layers of stretchy fabric and sewing up the sides.
