Use a seam ripper to remove the stitches at the lower ends of both zipper tapes. Remove about two inches of stitches on each side.
Use fine needle-nose pliers to pry off the metal stopper. Discard the stopper.
Thread the zipper tapes through the slider, and pull it up until locked teeth emerge behind it. Examine the entire zipper to ensure that the slider is positioned equally on both sides.
Thread a needle with thread that matches the zipper tape, and sew several stitches across the bottom of the zipper. These take the place of the metal stopper.
Replace the stitches you ripped out earlier, and reinforce other areas where the stitching between the zipper and the garment appears weak. If you have the time, sew along the entire length of both zipper tapes.
