Элегантный студийный модный портрет с S-образным изгибом

A refined semi-realistic digital fashion portrait of a slim adult woman against a [clean white] studio background, framed in a vertical composition from the upper thighs to above the head. She wears a [dark charcoal to black] satin camisole with thin spaghetti straps and subtle glossy sheen, paired with fitted high-waisted [black] trousers. Pose: An elegant S-curve silhouette with hips pushed to one side, torso gently twisted, relaxed shoulders, an elongated neck, and her head turned away in profile so her face is mostly hidden. Her arms hang gracefully in a dance-like posture, one hand rested low at her side and the other slightly bent outward with relaxed fingers. Her [dark brown] hair is styled in a loose, messy low bun with delicate wisps framing the neck. Lighting & Style: Soft high-key studio lighting with delicate skin gradients and subtle fabric sheen. Semi-realistic painterly fashion illustration style, smooth brushwork, clean contoured silhouette, understated luxury aesthetic, and a calm editorial mood. Constraints: Plain background only, no accessories, no props, no visible environment details.
