Leelee Sobieski, Miroslava Duma Style, Couture Fashion Week

Without a doubt, Paris Couture Fashion Week supplied a steady stream of enviable fashionista sightings, all worth a second glance. Among the mix: Diane Kruger, Hailee Steinfeld, Jessica Alba, and Carine Roitfeld turned out some of the sleekest front-row ensembles, despite wintry conditions — care of Chanel, Valentino, Christian Dior, Elie Saab, and more.

If the chic arrivals didn't provide all the styling fodder you need for your next cocktail party, then look to last night's glamorous Sidaction Gala for another round of inspiration. The fete marked the unofficial end of Couture Week but clearly did not mark the end of the A-list style parade. Leelee Sobieski stole our hearts in a bold floral-printed Christian Dior Spring '13 number, while Miroslava Duma continued her cool-girl reign in a masculine Giorgio Armani getup. Click through for all of the Sidaction Gala outfits, then catch up on all the best front-row moments from Paris Couture Fashion Week. — Additional reporting by Marisa Tom
