Amanda Seyfried’s been making the red carpet rounds in honor of the international premieres of her new movie, In Time, for a few weeks now. In LA, she wore a spring look from Prabal Gurung, and in London last night she rocked one of the season’s biggest trends—the short suit. It was everywhere in September: brightly colored at Jenni Kayne, slinky at Stella McCartney, preppy at Bill Blass and printed at Gurung, but Seyfried’s shiny blue suit hails from H&M. Think it works on the red carpet?
