The event was hosted by US Holocaust Memorial Museum at the Gaylord National Hotel & Convention Center.
The Oscar-winning actress looked incredible in her violet satin cocktail dress from the Fall 2006 collection, which was originally presented in a dark orange.
Natalie wore a pair of black Christian Dior pumps with bow detail. The dark color was appropriate as her dress featured a block of black on the back that floated towards the front sides. A sheer tulle inset sat above the bust and pretty embellishments adorned the shoulders.
Looking beautiful, as always, she completed her look with a halfway pinned hairstyle.
