Usually I think it's bad taste to show up to a designer's event in another designer's gown. But this time Katie Cassidy turned heads-- and in a good way--when she wore this orange Hervé Léger dress to the Miu Miu premiere of Lucrecia Martel’s “Muta” in Beverly Hills. While everyone else was wearing the latest ensembles from Miu Miu's fall line, Katie wore this Hervé Léger dress and completed her look with a pair of Jimmy Choos, Rebecca Minkoff clutch and Cartier accessories.
