This Week's Best Dressed Prove That Keeping It Simple Is Anything But

The star shone on the red carpet in this dark, sequined Dior dress, which she styled with black sandals and a simple clutch.

She looked pretty in pink at the Met Gala, but Kerry changed into a darker, gray Prada number for the afterparty. She opted out of pairing it with a necklace and went with some statement earrings instead.

Rosie always looks stunning, but this embellished Rodarte look was especially spectacular.

What a way to steal the spotlight in a not-so-simple black-and-white combo. This Dior dress — and those two diamond bracelets — looked lovely on Charlize at the Mad Max: Fury Road premiere without being too overpowering.

As Anna tours the globe promoting Pitch Perfect 2, we're bound to see tons of killer looks, like this black, white, and olive-green dress by Narciso Rodriguez.

We already know Selena can rock a swimsuit, but this dark, edgy leather and lace look from the Louis Vuitton cruise was superfierce.

Nothing says Spring and Summer quite like a bold romper. Chrissy wore this fun, bright blue piece at the Raye shoe launch event in West Hollywood on Thursday.

We always knew Sofia was a star, but now she's got one on the Hollywood Walk of Fame. To celebrate, she attended the event in a gold fit-and-flare Romona Keveza dress, which featured some brocade detail throughout.

Reese is all about the polished look. Instead of adding a bunch of chunky accessories to this blue tailored piece, she kept it simple with Jimmy Choo sandals and some Ana Khouri rings.

Gwyneth showed up to support her stylish mom, Blythe Danner, at the premiere of I'll See You in My Dreams in a white Creatures of the Wind mock turtleneck dress and some black heels.
