Oscar Fashion: What Will Rooney, Viola and Michelle Wear?

As Hollywood prepares for a glamorous night at the Oscars this Sunday,'s Lifestyle Editor Chassie Post predicts what to expect on the red carpet. "Designers are really clamoring to get their dresses on that red carpet," Post said, and in terms of bright colors, she anticipates "fuchsias, electric blues, emerald greens -- we've also seen a lot of nudes."

Of three of the five leading ladies up for Best Actress -- Michelle Williams, Rooney Mara and Viola Davis -- Post said, "Rooney wears black better than anybody on the red carpet, but we heard a rumor that she is going to wear color."

Chassie brought out a navy J. Mendel dress for Williams, saying, "Navy is such a fantastic color for Michelle. It's an unexpected turn on black and it's a really rich alternative."

Post pointed out that Viola has worn "almost every color of the rainbow, but we haven't seen her in this electric blue. She's got a strong silhouette that she loves to rock, but it's all soft and perfectly glamorous."
