At the same time bohemian style is finally finding its footing in fashion again, filtering down to the everyday woman on the street (in the most flouncy, folksy and fringe-filled ways possible), a new retro-inspired hair trend is taking off, with Amal Clooney piloting the flight.

Nicknamed “the bell-bottom blowout,” the fresh technique plays on the beloved bouffant styles of the 1970s, minus the wedge chop and shaggy layers. Modeled by Clooney, and crafted by hair artist Dimitris Giannetos, the “bell-bottom,” for the most part, is even-cut with long layers.
