Femme Fatale Shadowed In Emerald Neon

A classic femme fatale in her early thirties with a captivating mysterious aura, wearing a sleek emerald green satin gown with a high leg slit and delicate shoulder straps, holding a vintage dark lace fan partially covering her lower face, her dark eyes gazing directly forward with sharp intelligence, seated in a plush dark velvet booth of a 1940s hotel lounge, setting illuminated by a single glowing emerald green neon sign positioned behind slatted wooden blinds, casting long dramatic Venetian blind shadow strips across her face, neck, and satin dress, rich interplay of light green highlights and pitch-black shadows, background showing subtle dim crystal glassware on a dark mahogany table, medium portrait framing centered on the subject, captured on a 50mm f/1.4 lens, razor-sharp focus on subject's eyes while background fades softly, dramatic chiaroscuro lighting, retro noir cinema aesthetic, sophisticated visual elegance.
