15. WORST: Jessica Chastain’s pink Balenciaga gown was a little too powerfully hued for her and appeared a little too large. She completed her look with Palladium black and white diamond stud earrings. 17. BEST: If anyone else wore this Van Gough-esque Rodarte dress, they would be banished to the worst dressed list, but the young and vibrant Elle Fanning managed to make it look easy and breezy.
