Best-Dressed Models and Celebrities Week of August 13, 2012

The cool kids kept it coastal this week — and the styles were just as eclectic as the locales. In New York, Prabal Gurung and company celebrated the arrival of the designer's ICB collection at Barneys with tacos, popsicles, and a lively set by indie-dance duo Tanlines. Hanne Gaby Odiele, Elettra Wiedemann, Dani Stahl, Leandra Medine, and Mia Moretti — who also pulled double duty as DJ — were among those in attendance; some even sported looks from the just-in collection. "Tonight is all about celebration, love, support," Gurung told the crowd before the band took the stage at the retailer's darkened Chelsea Co-Op store.

Over in Los Angeles, there was another young label celebrating the launch of its collection at Barneys as well: Vena Cava. Hosted by Gen Art, the party featured a gaggle of Cava gals — including Tennessee Thomas, Malin Akerman, Jenny Lewis, and Busy Philipps — sporting the brand's Fall 2012 looks while St. Vincent performed to a packed-in house at Chateau Marmont.

A peek at all that — plus all of the gorgeous ensembles worn by Jessica Biel and Kate Beckinsale on their Euro tour for Total Recall — here, in our weekly best-of recap.
