We've already decided that the bob haircut is the style to try in 2014, and Katy Perry  is the latest to hop on the trend. InStyle  has all the details.
Just because Katy Perry  has retired her day-glo hair hues, that doesn’t mean she’s done experimenting! Over the weekend, the singer revealed her new shoulder-skimming cut and layered fringe, shortly after snapping a picture for Instagram . It’s no secret that Perry loves experimenting with her look, constantly drawing inspiration from the films, books, and TV shows she’s currently loving. “Comic books, Blade Runner, Lolita — so many inspirations come into play when I’m doing my hair and makeup,” the star told InStyle previously. “Every morning I think, who am I going to be today?” While the jury is still out on Perry’s most-recent hair muse, we’re getting a slight ’20s-era Louise Brooks feel from the short length and face-framing bangs, while the tousled texture holds a ’90s grunge vibe.
