How do I fix a broken zipper?

First, start by identifying where the zipper is stuck. If the zipper is stuck on one side of the garment, try gently pushing it up, starting from the top of the zipper. If the problem is at the other end, push the zipper down from the bottom. If necessary, use a small pair of pliers to gently pull away any fabric or thread that is stuck in the zipper. If the teeth of the zipper are not lined up correctly, try zipping and unzipping the zipper several times to align them. If necessary, use a wax pencil to lubricate the teeth of the zipper, which can help the zipper move more smoothly.
