Allison William’s ‘Girls’ Premiere Look

Williams arrived at the premiere in a midnight blue Monique Lhuillier ensemble, which included a sheer skirt that featured jeweled appliqués. Her makeup look featured a smokey eye, and she wore her hair in an undone french twist.

New York Stylist, Dominick Pucciarello, designed Williams’ hairstyle look. “We wanted a Brigitte Bardot feel for the premiere of Season 4 of Girls,” he told HollywoodLife.com. “We really wanted a loose, sexy feel for her hair.”

Prior to the big night, Williams shared a trio of throwback snaps of Girls‘ premiere parties past.
