Heading toward eternal damnation and don't have a thing to wear? Take a cue from the snappy dressers in the heaven-versus-hell action flick Constantine. ''[Director] Francis Lawrence really wanted me to capture the off-kilterness of having hell in L.A.,'' says costume designer Louise Frogley (Spy Game, Traffic), who dressed Keanu Reeves' antihero in early-'60s-inspired slim black pants, skinny ties, and a sleek, short raincoat not exactly sunny L.A. gear, but just right for a resuscitated warrior seeking salvation. As for Gavin Rossdale's demon, Balthazar, Frogley remembered the '80s with a sharply cut cashmere pin-striped suit: ''I wanted him to look like a horrible English sybarite bastard, very aggressively right-wing,'' she laughs. If you're gonna be damned, you might as well be damned hot.
