Sharp, realistic full-length photograph of a short black strapless silk satin and lace dress by designer Yves Saint Laurent worn by a 20-year-old Italian woman walking down the catwalk in a large hall of a major international fashion show. She has very long, straight, windswept red hair, bright, expressive blue eyes, and a fair complexion with very few freckles but none on her nose. Her expression is serious, enigmatic, and subtle, capturing the essence of the mysterious smile of the Mona Lisa. The lighting is soft and professional, highlighting her youthful, confident demeanor.
