Park City, Utah was swarmed earlier this month with stars for the Sundance Film Festival. In between junkets and screenings, celebs slipped over to the Solstice Sunglasses Boutique in the Bertolli Meal Soup Chalet hosted by GenArt and the CWPR’s RE: Treat Lounge to snag some of the hottest shades for spring. Laura Prepon slipped on a pair of Tommy Hilfiger sunglasses to match her ski bunny outfit after losing her old pair flew off the roof of her car. Kate Bosworth, Lake Bell and Katie Aselton were in town to premiere their movie Black Rock and stopped in to try a few styles on as well as discuss skiing compared to snowboarding. Kate gave the other girls fashion suggestions, pointing out a pair of Marc Jacobs sunglasses for Lake, who ended up with a pair of Yves Saint Laurent shades. Emily Blunt popped into the boutique while promoting her new film, Your Sister’s Sister, to get herself “a good aviator.” She left with a pair of Bottega Venetas and a pair of YSLs to show off to her husband John Krasinski. Andie McDowell attended the festival for charity. She slipped on a pair Marc Jacobs sunglasses and reminisced about her start in the industry in Sex, Lies and Videotape with a friend before heading back out in the cold.
