Stepping out to promote her new movie, Sienna Miller headed to the premiere of "Just Like a Woman" in New York City on Wednesday (June 5).

The "Layer Cake" star kept things simple in a classic sleeveless little black dress with matching heels as she posed for photos outside.

In the drama, a Chicago housewife runs off to Santa Fe with a friend to compete in a belly dancing competition.

Directed by Rachid Bouchareb, the film also stars Golshifteh Farahani, Bahar Soomekh, Tim Guinee, and Roschdy Zem. "Just Like a Woman" hits theaters on July 5th.
