11 ways to fix a broken zipper - best tips and tricks

But let's not get ahead of ourselves as it isn't always an easy fix. In fact, broken zippers are arguably the most awkward fashion piece to repair because, the more you try and move the slider up and down (in various states of distress), the more broken the zip can become.

While you can take a dodgy zipper to your local alterations shop for a replacement, if you're on your way out and your dress or bag suddenly breaks, you want a quick and simple solution. Plus, taking it to an expert means it'll cost you, so trying to fix the zipper yourself is a cost-free benefit.

Here, as part of our 'How to' Style Lab series, we round up the best zipper repair tricks using household items such as Vaseline, pencils and even nail polish – depending on what you have lying around.

First things first, let's have a little zipper anatomy lesson. If you know what each part of the zipper is called, it'll be easier to fix your zipper problem. Or at least ensure the instructions for fixing are as clear as possible. Use the diagram below to familiarise yourself with the teeth, slider and puller.

It's not rocket science, so without further ado let's move on to those easy, fast solutions to fix a zipper and get you on your way again.

Does your zipper seem to work properly but then, as soon as it's fastened, all the teeth come undone? If so, the problem is the slider (AKA – the piece that's meant to lock the teeth together). Over time, these sliders start to loosen and gape, which makes them less effective at fixing the teeth in place. While you can take your garment to a tailor to replace the entire zipper, there is a simple, more affordable hack you can try first (because nobody wants to fork out on a whole new zip if you can easily fix the one you already have).

While the slider is still attached to the garment, reach for a pair of pliers. The part of the slider that attaches to the puller (on the outwards facing side of the garment), is called the top plate. The part of the slider that faces the inwards side of the garment is then called the bottom plate. Use your pliers to pinch the top and bottom plate together to help restore the slider to its original, tighter shape. An easy way to gauge whether the pliers are working is to check that the gap between the two places (where the teeth live) is getting smaller.

Be careful not to press too hard as too much pressure can break the slider. The aim is to do this gradually, compressing the plates on either side of the puller until it's nice and tight.

If one or both sides of the slider come off the track, the zipper doesn't necessarily need replacing, the slider just needs reattaching. To do this, find the 'bottom' of the zip. The part that is, typically, the end closest to the floor when you're wearing the garment. If you can't tell which is the right way up, look for the end with a square tab of fabric after the zip finishes.

Then, feed the teeth from that end into the slider. If you need extra leverage to push the teeth into place, use a flathead screwdriver. Once the teeth are inside both sides of the slider, use the puller to move it up and down the track to lock it in place.

First, check to see if there's anything caught in the zip, like the lining of the garment or rogue fibres. If possible, remove these obstructions by hand before retrying the zip.

If, however, the stuck object won't move, try going in with a pair of tweezers to slowly pull the blockage out of the teeth. Sometimes softly wiggling the puller up and down as you tug on the slider can also help dislodge tougher items.

If the zip still won't budge, don't lose faith. You might need to give it a little extra help. Start by using a pencil to coat the teeth surrounding the lodge with a light coating of graphite – this will act as a lubricant to help facilitate a smooth run. If that fails, and you can easily wash the garment afterwards, try a small amount of washing up liquid, to furthe
