Retrato Editorial de Alta Costura con Vestido Voluminoso

A photorealistic high-fashion editorial photograph of a young [Asian] woman with a slim-thick hourglass figure, tall statuesque stature (approx. 170cm), and smooth fair skin. She stands on an elegant interior marble staircase in a dynamic pose: leaning slightly backward, head tilted upward in joyful laughter, right hand gripping a sleek black railing, left hand on her hip. Her dark hair is styled in a sleek, polished low bun. She wears a voluminous tiered ballgown of brushed, paint-effect fabric cascading down the steps, featuring an ombré palette of [vibrant electric chartreuse at the bodice, transitioning through bright lime green tiers, and fading into deep forest-charcoal] at the hem. Natural daylight streams through large arched windows, casting luminous highlights on the textured fabric and soft shadows on the stairs. Shot on a [50mm] lens, f/2.8, sharp focus on expression and couture details, high-end fashion magazine aesthetic.
