These vixenish vamps have turned up the heat on the red carpet. No matter the silhouette — Grecian-inspired o ne- shouldered dresses, frothy frocks, or voluminous caftans — a rosy hue is a bona fide head turner. The ultimate siren trifecta of Angelina Jolie, Salma Hayek, and Christina Hendricks opted for body-con gowns. Leading ladies like Julianne Moore and Frieda Pinto went in for shorter dresses with asymmetrical draping. Natalia Vo dianova, Dree Hemingway and Charlotte Casiraghi fanned the flames with unexpected flourishes.
