Allison Williams ain't your ordinary girl.

The Girls star stunned in red at the Robin Hood Foundation Gala. The actress wore a strapless gown with a full skirt. From her bright red lipstick to her simple black stilettos, she was head-to-toe perfection. Her character Marnie would approve.

Allison, who's the daughter of NBC Nightly News anchor Brian Williams, is currently filming the upcoming third season of her HBO series. She recently told TV Line that her on-screen love interest Christopher Abbott's abrupt departure had "a huge effect on our show and [on the character of] Marnie specifically. ... It's unfortunate that [Abbott] is no longer a part of the family."

Uma Thurman, Katie Couric, Bethanny Frankel, and Gayle King were some of the other celebrities in attendance. Uma looked elegant in a floor-length white gown and brown coat. It's hard to believe that the Kill Bill star, who recently showed off her enviable curves in a striking green gown at the Met gala, had a child less than a year ago. Luna's mama has never looked better!
