Rooney Mara is a Lady in Navy Blue J.W. Anderson at the 2013 L.A. Film Festival

Call it a curtain part, former lampshade or fancy bustier — Rooney Mara rocked whatever she was wearing on Saturday as she hit the 2013 Los Angeles Film Festival.

The 28-year-old actress, who was on hand to promote her new film Ain’t Them Bodies Saints, was a vision in a navy blue creation by J.W. Anderson. Going accessories-free, Mara let her outfit do all the talking as she posed for photos with co-star Casey Affleck and director David Lowery (who let his moustache do all the talking).

In other Rooney Mara news, her next film will fall into the category of science fiction romance. Her, directed by Spike Jonze and starring Mara, Joaquin Phoenix, Amy Adams and Olivia Wilde, is due in November.
