Best Celebrity Style | Oct. 12, 2012

In the way of ultrachic celebrity snaps you probably didn't see this week (because we're hoping you already gave the glam lineup at this week's Chanel fete and amfAR Gala a look), it's a bevvy of both casual ensembles with a cool-girl tilt and evening-ready eventwear from the likes of Keira Knightley and Solange Knowles. While Solange took a sleek, sexy angle in a cutout Esteban Cortazar sheath, Keira Knightley played it ladylike in Chanel at the label's little black jacket dinner in London. As for the rest, we're feeling inspired by Freida Pinto's polished black-on-black separates and (yet another) enviable outfit from girl crush Kate Bosworth. The top 10 starts right here.
