"Brian is very much about fashion," says the film’s costume designer Olivier Bériot. "He knows the designers, he knows what he likes." In fact, even before Romijin-Stamos was cast, Bériot and De Palma mapped out her 12 costume changes, from a white Valentino suit to Christian Dior HotPants to Dolce & Gabbana’s coat to La Perla lingerie.
"Absolutely, the costumes helped," says Romijn-Stamos. "We really camped it up at times." Like Melanie Griffith, who vamped in black stilettos and a G-string in De Palma’s "Body Double" in 1984, Romijn-Stamos gave her heart and soles to "Femme Fatale’s" pivotal scene, in which she seduces fellow model-turned-actress Rie Rasmussen in a bathroom stall before stealing her gold and diamond Chopard bustier. The audience, however, will see only Romijn-Stamos’ Louboutin boots and Rasmussen’s Rodolphe Menudier sandals doing a tango beneath the stall door. "It’s much sexier to have the shoes make love, no?" asks Bériot.
