Keira's 'Anna Karenina' Premiere Style
Knightley channels the film's dark romance with her red carpet style.
Christmas came early on the red carpet this week, with almost too many buzz-worthy fashion moments to count.

From the star-studded premieres of some of the biggest holiday blockbusters to fetes honoring Glamour and GQ‘s women and men of the year, respectively, and fashion’s up-and-coming designers, there were plenty of red carpet events for showcasing the latest trends.

Twilight stars Kristen Stewartand Ashley Greene kicked off the week in style at the much-anticipated world premiere of The Twilight Saga: Breaking Dawn 2 in L.A. on Monday. And the cast kept the fantastic fashion coming as they split up to promote the film in New York and Spain.

Meanwhile Keira Knightleys wardrobe for her U.S. Anna Karenina promotional tour this week — including the custom Erdem  green gown she wore to the film’s L.A. premiere —  gave us just as much to talk about as her on-screen costumes.

At the Vogue/CFDA fashion awards, the fashion crowd, including Emma Stone and Christina Ricci, showed us how to work all the hottest holiday styles.

And across the pond, Kate Moss celebrated the launch of her new book by showing us why she’s a style icon in glamorous gold and leopard looks.

While there were plenty of style stars who showed us how to get it right this week, there were those that offered a lesson in what not to do.

From the week’s hits to the misses, we’ve rounded up all the week’s most notable fashion.
