ラグジュアリー階段セルフィーポートレート - エディトリアルファッション

A full-body editorial fashion portrait of the person from the uploaded reference photo, sitting sideways on a wide, modern light-wood staircase. The subject is wearing a luxurious black satin mini slip dress with a draped cowl neckline and thin spaghetti straps, paired with black strappy stiletto high-heels. Her left leg is elegantly crossed over her right knee, showcasing the shoes. She is holding a dark smartphone in her right hand near her face, actively taking a high-angle selfie, and looking towards the phone. She has manicured red fingernails. The setting is a minimalist luxury home interior. The wooden stair treads are individually backlit by warm linear LED lights (3000K), creating horizontal lines of glow. Clear glass railings with black metal posts frame the scene. Shot from a slightly low angle (worm's-eye view) to emphasize height. Soft diffused studio lighting on the face, contrasting with the dramatic stair lighting. 8k resolution, photorealistic, cinematic realism, high-fidelity satin texture.
