The Great Gatsby world premiere took place in New York City last evening, and Baz Luhrmann's cast came out to celebrate. Carey Mulligan stood out in a bold red Lanvin look that's in-line with her minimalist approach to red carpet dressing. In the movie, Carey wore a bevy of decadent '20s-inspired Prada gowns along with loads of diamonds and pearls, and she told us that she was nervous wearing it all - she even broke her pearls a few times! For all the style scoop from the Gatsby premiere, watch today's Fashion Flash. On Allison: Rebecca Taylor jacket, Zara top.
