They say good things come in threes — such was the case with this trifecta of pre-Oscars fetes that drew out a very chic guest list of this year's nominees. Leading ladies Jennifer Lawrence, Anne Hathaway, and Jessica Chastain all celebrated at their respective LA parties, showing off another round of red-carpet-worthy wear in preparation for this Sunday's big event. Jessica Chastain arrived at the TheWrap's fourth annual pre-Oscars fete in a bright Andrew Gn cobalt sheath and subtle nude pumps. Jennifer Lawrence stepped out in an architectural black-and-white Roland Mouret strapless to celebrate Silver Linings Playbook with VF, Barneys, and the Weinstein Company; while Anne Hathaway, clad in Theyskens' Theory, joined her Les Mis costars at yet another VF-hosted event to celebrate her film.
