Best Dressed Celebrities and Models Week of June 25 2012

In a burgundy and white dress from Chanel's Resort 2013 collection at the Los Angeles premiere of The Amazing Spider-Man, Emma Stone continued her recent trek of chicness — but there were other knockout looks this week as well. Sofia Coppola, for one, who got a head start on Resort 2013 when she wore a sequin striped number from — who else? — good pal Marc Jacob at the amfAR Inspiration Night in Paris. Dita Von Teese also sported Marc Jacobs at the amfAR event; the actress chose a sparkling brocade from the designer's Fall 2012 collection.

In London, the Serpentine Gallery Summer Party, hosted by designer Leon Max, brought a stunning crowd and an equally stunning assortment of ensembles: Laura Bailey, Erin O'Connor, Cara Delevingne, Florence Welch, Clare Waight Keller, and Caroline Sieber (left) were among those who turned heads.

All those — plus Rose Byrne, Blake Lively, Karlie Kloss, Daphne Guinness, and more — here, in our best-of-the-week slideshow.
