One-shouldered dresses and vibrant crimson gowns dominated the red carpet at the Screen Actors Guild (SAG) Awards this weekend. Mariah Carey, "Mad Men" star Christina Hendricks, and other ladies captivated in red, while celebrities like "30 Rock's" Jane Krakowski and French actress Marion Cotillard were one of the many who opted for the single shoulder look.

Sandra Bullock was named Best Actress for her performance in The Blind Side. She won the same award at last week's Golden Globes. Mo'nique took home Best Supporting Actress for Precious, while Tina Fey and Julianna Margulies claimed the statues for TV comedy and drama, respectively.
