No jeans here!
Stars went all out at The Great Gatsby premiere in New York City tonight. Carey Mulligan stunned in a red Lanvin number with Tiffany and Co. jewels.
Not that the dudes weren't looking dapper themselves. Leonard DiCaprio, Tobey Maguire and Jay-Z all cleaned up nicely in well-tailored suits.
Another highlight? Isla Fisher looked lovely in a floral Dolce & Gabbana dress.
