Reese Witherspoon was the only woman there who did not look absolutely fantastic. (Okay, I could do without Nicole Kidman's feathers too.)
Anne Hathaway, Marisa Tomei, Meryl Streep, Kate Winslet, Natalie Portman, Penelope Cruz...everyone looked completely, perfectly beautiful.
ETA: Mily Cyrus's outfit was just deranged. And not at all age-appropriate.
