Supporting actress nominee Jessica Chastain (A Most Violent Year) sparkled in a bronze Atelier Versace halter gown with a plunging neckline and Piaget diamond shoulder-dusters. Meanwhile, Gina Rodriguez—who has won TV viewers’ hearts on The CW’s telenovela spoof, Jane the Virgin, and nabbed a Globe for her portrayal of the super-lovable accidentally artificially inseminated title character—stole the style spotlight in a strapless Badgley Mischka gown and diamonds from go-to red-carpet jeweler Chopard. Now, because we love Diane Kruger and her impeccable style, we can forgive her any number of sins—such as mispronouncing Kwiat during a preshow interview. She looked breathtaking in her shimmering silver Emilia Wickstead gown, and those KWEE-aht diamond cluster earrings practically lit up her face.
