Once an 80s fashion staple, or a handy gym accessory, the easy-to-carry pouch has been seen draped round many a celeb's middle over recent months.
With fashionistas such as Rihanna and Rita Ora daring to"bring back" the bum bag, the high street is sure to follow.
But they're not the only celebs ditching their trusty totes for the bum bag.
Kim Kardashian, Karlie Kloss and even Liam Payne have all been spotted out and about with them.
So, will you be trying out the trend?
