Thankfully our great friend, the internet, has once again produced the goods, dishing up an actual proven-to-work hack that has since gone viral, and taken the style blogs by storm. It's true, they have found a way to make sure that our zips stay zipped. You can once again wear your favourite jeans without fear that you'll also be putting on an unwelcome show.
The 3 step hack seems like a failsafe way to keep your fly up, and allowing you to go about your day, worry free.
Find a metal loop, the kind that is common on most key-rings.
Attach the loop to your zipper by threading it through the small metal opening at the end.
Pull your zipper to the top of it's tether, and then hook the metal ring over the button on your pants.
