Create a 15-second ultra-luxury cinematic YSL Eau de Parfum advertisement featuring the same elegant adult Korean woman with long glossy black hair, sophisticated makeup, refined jewelry, a champagne-gold couture gown, and elegant heels. Set the entire commercial inside a grand royal mansion with marble floors, sweeping staircases, golden details, crystal chandeliers, warm candlelight, and cinematic shadows. Show her gracefully descending the staircase, confidently approaching a marble table, picking up the YSL perfume bottle, and holding it beside her face before gently spraying it on her neck. Capture premium close-ups of her expression, the perfume mist, and the bottle with beautiful golden reflections and shallow depth of field. She then walks confidently through the mansion as the final shot reveals the YSL Eau de Parfum bottle centered on the marble table with warm lighting, flowers, candles, and a subtle lens flare. Add elegant orchestral music, soft piano, strings, realistic footsteps, fabric movement, perfume spray, and subtle ambience. Maintain perfect consistency in the woman, outfit, jewelry, perfume bottle, environment, and lighting throughout. Ultra-realistic, photorealistic, cinematic, high-fashion luxury advertising style, smooth camera movement, realistic reflections, natural expressions, premium international perfume campaign aesthetic. Add elegant voice-over: “YSL Eau de Parfum… the essence of elegance. Confidence in every spray. Beautifully refined. Long-lasting. Made to stay with you.” End with a clean luxury fade to black.
