SAG Best-Dressed SLIDESHOW: Jessica Chastain Sizzles On Red Carpet

Jessica Chastain wasn't just a nominee for her role as Maya in Kathryn Bigelow's Zero Dark Thirty at Sunday night's Screen Actors Guild Awards ceremony — she also occupied one of the top spots on most people's Best Dressed lists, after she showed up on the red carpet in a stunning crimson gown by Alexander McQueen, accented with a tasteful-yet-plunging silver necklace.

While the award for Outstanding Performance by a Female Actor in a Leading Role ended up going to favorite Jennifer Lawrence — who also looked fabulous in Christian Dior, despite her wardrobe malfunction — for her role as Tiffany in Silver Linings Playbook, the entire category was chock-full of well-dressed actresses. Naomi Watts, who was recognized for her role in The Impossible also made heads turn, decked out in a white, patterned Marchesa gown.
