Mary-Kate and Ashley Olsen won womenswear designers of the year for their work on The Row at last night's CFDA Awards in NYC. MK debuted a darker 'do to match her all-black look, while Ashley mixed things up with a pretty purple number from their award-winning line for the exciting evening. The celebrated twins were joined by some of the biggest names in fashion, including Rachel Zoe, Kate Bosworth, and Zoe Saldana. Rachel was in a dress of her own design and tweeted a photo of herself and husband Rodger Berman looking dapper as they stepped out to the event. Zoe Saldana's Prabal Gurung gown was particularly jaw-dropping, while Jessica Chastain donned her own girly concoction from the same designer. Busy Philipps looked sexy in her tight pants number, while Julianne showed some skin in her red Kaufman Franco bit. Fashionologie was on the scene for all the action, so check out the CFDA red-carpet and behind-the-scenes highlights, and stay tuned for lots more action from the big night!
