Best Dressed of the Week: March 21

Red and yellow and green, oh my!

Our favorite Hollywood stars ushered in spring fashion this past week, taking their red carpet looks to new heights. Olivia Wilde opted for an emerald green Marc Jacobs dress for a red carpet premiere for "A Vigilante" and Amanda Seyfried looked poised as ever in a red ruffled Jason Wu dress.

Meanwhile, a smiling Julia Louis-Dreyfus was the epitome of sunshine in a bright yellow Escada dress for a press day in New York, as model Duckie Thot rocked a hot, magenta pantsuit for an evening with Rita Ora.

It was back to the basics for Mandy Moore and Uma Thurman, who both donned chic LBDs for their respective red carpets, while Nicole Scherzinger and Ashley Graham looked to metallics for theirs.
