At last night's Women in Hollywood dinner hosted by Elle, the A-list crowd was out in full force, and the ladies celebrated each other with some gorgeous hair and makeup. It seems the winning beauty trend of the night was the ponytail seen on Emmy Rossum, Lake Bell, and Naya Rivera, to name a few. At a close second was the classic chignon, which was the style of choice for Reese Witherspoon and Marion Cotillard among others.

Last night's 20th Annual Elle Women in Hollywood event celebrated the best performances and contributions from women working in the film industry, including rising stars like Shailene Woodley and established talents Marion Cotillard and Reese Witherspoon. Calvin Klein was one of the event's sponsors, so it's no surprise that many of the attendees were dressed in Francisco Costa's designs. There were a few surprises though, including Emmy Rossum's red Elie Saab cocktail dress and Naya Rivera's plunging white Pamela Rolland jumpsuit. Pale shades or pops of girlie color were the name of the game at the event, with lots of white and red and only a handful of attendees opting for black.
