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.
