Last evening's premieres of Carol (starring Cate Blanchett and Rooney Mara) and the Italian classic Rocco and His Brothers saw thespians and models showing up in both simple and extravagant frocks donning the deepest, most seductive jewel tones. Erin O'Connor's Ralph and Russo Couture ruby frock was outshone by a dramatic bow, while Aishwarya Rai expertly matched the emeralds in her Elie Saab dress to her lower lash line. See our favourites below.
