Style Superstar: Kate Mara Amazes In Acid Chiffon

With glum, gray winter coming down the pike, we always appreciate an eye-popping wake-up call from Hollywood's best-dressed—particularly when it comes in the form of a shocking chartreuse dress styled like whoa. And during the month of November, to our great delight, two different stars opted to throw a little acid green on the red carpet! Whose look was the searing superstar?

It's Kate Mara! Her Jason Wu dress at the "Deadfall" premiere was one of the event's most noticeable outfits, for obvious reasons—but with a lovely Grecian-style drape, an embellished lace inset, and the addition of strappy black shoes and jewelry, this was an eye-catching look that we couldn't look away from. And with Kate wisely opting for sleek hair and smoky eyes to put some polish on her ensemble, she's a hands-down win for Style Superstar.

And if you're thinking that shade of green seems familiar, you're right: it's a close cousin to the bold dress that Kristen Stewart wore to the Madrid premiere of "The Twilight Saga: Breaking Dawn - Part 2." But where Kate hit all the right notes with her chiffon-draped dream dress, Kristen missed the most vital rule of wearing a color this bright: It needs to fit. Like, really, really fit. And while KStew nailed it with the length (those legs!) and the styling (those shoes!), the cap-sleeved cut and creasing at the waist makes it look awkward. We'd love to see her in a version of this look that's a little more flattering to her figure.
