A cinematic high-fashion photorealistic shot of a beautiful brunette woman in her early 30s with long dark wavy hair. She has a curvy silhouette, firm, perky, medium-sized breasts, a defined waist, and proportionate hips and thighs. She sits on the marble steps of a grand old mansion staircase, legs crossed, body leaning slightly forward. She wears an elegant long dress with a high side slit and stiletto heels. One hand rests on the step behind her, the other on her knee. She looks directly at the camera with an intense, penetrating gaze. Soft elegant lighting, sophisticated and sensual atmosphere. Shot on 35mm lens, editorial fashion style, shallow depth of field, ultra-realistic texture, natural body proportions.
