For Sunday's Academy Awards in Los Angeles, Kate Winslet went back to basics. She selected a black, slightly shimmering strapless gown from Ralph Lauren to attend the show. The piece was custom-made for Kate, and made of silk lamé. She kept her accessories light too, wearing danging diamond earrings. The total effect was something Ralph's team dubbed "stunning" in a post on Twitter. But Ralph wasn't the only main main during Kate's night, as she also walked the red carpet with Leonardo DiCaprio.
