Katy has so many different patterns and designs, however, that she manages to make each one look completely fresh and original. Now that's the way to make a trend your own, right there.
The bow band addiction seems to have happened since Katy's been wearing her hair super-straight and bobbed with a blunt fringe.
And why not? It totally works.
Just yesterday (4 March) we spotted Katy in this simple black Alice band (above) while she was in Sydney to announce the Australian leg of her Prismatic world tour which kicks off in November.
Wearing a white, cut-out peplum dress and black and white accessories, the headpiece was the perfect topping to a fabulous monochrome look.
She's also rocked stripes, polka dots and baby pink headbands in the last 2 weeks alone!
And we particularly loved the black and white striped number she rocked at the U-Express Live 2014 press conference in Japan on Monday (3 March) while wearing a McDonald's-inspired Moschino outfit (below).
Cute, thin headbands are a great accessory choice for spring and work especially well for festivals as they're great for scraping back an unwashed fringe!
They're also one of the few accessories you can wear with super-short hair, a la Oscar-winning actress, Lupita Nyong'o.
So there's nothing else for it, ladies, but to get totally involved. Check out a few of our high-street favourites below...
