Expert Answer

Some old zippers can be stopped from unzipping by simply locking them at the top. First, make sure the garment is zipped all the way to the top, then press the zipper pull down as if you are snapping it to lock. Sometimes,if a zipper doesn't lock, it may need replacing.

Question

I have a dress that zips up the front and the zipper keeps coming undone and exposing my chest. What can I do?

Community Answer

You could always use a safety pin and fasten it from the inside of the dress so only a little bit of the metal is showing. Depending on the color of the dress, it shouldn't be too visible.

Question

How to make a purse zipper keep from unzipping?

Community Answer

You can use the rubber band method by tying the rubber band to the hole in the zipper, doing up the zipper, and then attaching the rubber band to the handle of the purse. Alternatively, you can try replacing the zipper slider on the purse with a new zipper slider so it zips up properly.

Question

Zipper on a jacket pulls apart; what can I do?

Top Answerer

The zipper pull itself is opening up from the constant pulling. Instead of replacing it, close up the gap. Bring the zipper pull to the base, but leave some teeth on both sides of it. Squeeze the top and bottom of the zipper pull with pliers enough so there is no loose gap between it and the teeth. The pull will not align the teeth of the zipper to interlock properly when it develops too wide of a gap, which results in the teeth pulling apart.
