It's a truly worthy cause, so we're glad to see that the stars stepped out in style for the charitable gala benefitting the American Cancer Society. And when it came to the red carpet, everyone earned high marks in the fashion department.
Host Reese was glowing in a bright orange Roland Mouret dress with a plunging neckline and white panels on the side. And fellow blonde Gwyneth Paltrow looked absolutely stunning in a cobalt blue David Koma cutout dress. We're having some major ab envy right now!
And then there was Selena Gomez, who also went for the cutout trend in a white wide-legged jumpsuit, and Anne Hathaway showed her love for the menswear trend in a Viktor & Rolf bedazzled blazer.
Another stunner? Jessica Alba, who looked simply beautiful in a dark berry lip and a white leather floral Ralph Lauren dress.
