Elegant Woman Portrait in a Marble Bathroom

Use the provided reference photo of a single woman strictly to preserve her exact facial identity, natural body proportions, and physique, while completely disregarding her original pose, attire, and background. Depict her sitting gracefully on the edge of a luxury white marble bathroom countertop, angled toward the camera with legs bent forward and one hand resting gently on the marble surface beside a sleek undermount sink. She gazes directly into the lens with a gentle, enchanting smile and a soft, confident expression. She wears an ultra-glamorous, semi-sheer mini dress featuring delicate spaghetti straps, a plunging neckline, and a sheer grid pattern embellished with shimmering circular pastel-holographic sequins reflecting soft lavender, pink, and silver tones. The upscale modern bathroom setting includes polished neutral wall tiles and a brightly illuminated vertical vanity mirror casting soft ambient light, with her reflection subtly visible behind her. A striking luminous rim light and hair glow accentuates her voluminous dark wavy hair, separating her cleanly from the background. The atmosphere is bright and luxurious with creamy, glass-skin skin tones and vibrant, neutral color grading. Aspect ratio 4:5.
