The Best-Dressed Stars This Week: 9/13/13

Naomi Watts stunned at the Paris premiere of Diane! Not only is the detailing on this Marchesa dress exquisite, but her Chopard jewels make the whole look.

Can we just take a second to discuss Alice Eve's hot bod? Damn girl! But also loving your Catherine Deane dress, obvs.

Who says you can't rock white after Labor Day? Karolina Kurkova killed in in Camilla and Marc's white 'Distinguish' dress at the Popplicks: Plus One book launch event.

The print on Keira Knightley's Mary Katrantzou is so whimsical—exactly the kind of frock that's meant for a red carpet premiere, or say tea with the Queen?

Pretty Little Liar Sasha Pieterse attended the LA premiere of Insidious: Chapter 2 in a lacy Romona Keveza LBD and Bionda Castana 'Joan' black suede heels—so cute!

Loving everything about Michelle Dockery's ensemble at Fashion Week, especially her Nancy Gonzalez silver croc clutch.

C'monnnnnnn it just doesn't get any hotter than Minka Kelly! This curve-hugging dress is maj as are her Jamie Wolf earrings and Graziela Gems bracelet.

Jamie Chung looked adorable in Ann Taylor's 'Derby Polka Dot Dress' while attending The Cut and New York Magazine's Fashion Week Party with Revlon and Ciroc at Gramercy Terrace at The Gramercy Park Hotel in New York City. A girl can't go wrong with this classic pattern.

Not only is this one of my favorite dresses this week, it might even make my faves for the month. Scarlett Johansson's Vivienne Westwood purple and white, polka dot, corset dress at the Under the Skin premiere at TIFF was girly, sexy, and memorable in all the right ways.

Take a style cue from Olivia Wilde and always pair a bright lemon-yellow dress with a bright-pink lip. It obviously works well.
