All you need is an old suit or two, your machine (or you can hand stitch) and half an hour. If you're not good with a needle, check out my new no-sew version!
Simply cut your one-piece horizontally, pin and zig-zag stitch (to account for the stretch). If your suit doesn't have much stretch left you'll want to insert elastic or add darts. Do the same for the top and voilà!
