Stars showed up to honor Matt Damon at the American Cinematheque Awards in Beverly Hills on Saturday, where they were decked out in the hautist of couture.  Charlize Theron stunned in a color-fading, seafoam green Givenchy mini, which showed off her long, slender legs.  The blonde beauty rocked black booties and a matching clutch for an edgy and fashionable finish.

Jennifer Garner also dove into the oceanic color scheme, wearing a navy and black J. Mendel strapless, paired with black heels and a clutch.
