Zoë Kravitz has worn waist-length box braids for quite some time. But, just in time for summer, the actress sprang for the crop. These days — according to her Instagram — she's got a perfectly tousled chin-length bob. And, while we're definitely sorry to see her signature style go, this look totally suits her. It's fun and youthful, but still a little bit edgy — pretty much like the star herself. This wasn't a just-for-fun chop, though. Kravitz is set to star as Christina in the installment of the Divergent trilogy: Allegiant. The mini-makeover was for the role. Way to commit, girl.
