Who: Rooney Mara

Where: A Downtown Calvin Klein-sponsored screening of IFC Films's Ain't Them Bodies Saints at the Museum of Modern Art in New York.

When: August 13

What: A cropped, navy top and black skirt, both from Calvin Klein Collection fall 2013.

Why: Yes, it's August, but most fashion girls already have fall on their minds—if not their bodies. Trust Mara to remind us of dark, chic things to come.
