Pick a pair of your used and well-fitted high-waisted jeans, and mark the length you want the short to be as short as. With tailor scissors, cut the extra length off the denim. Always mark it in a way that you have space for errors. You can make them distressed or frayed to add definition and funk. Sew the ends for a neat finish. High-waisted shorts are quite easily the sexiest looking shorts you can wear.
