High-Fashion Selfie Portrait in a Modern Luxury Home

A full-body, high-fashion portrait of a stunning young woman. She is wearing a black satin mini slip dress with a draped cowl neckline and thin spaghetti straps, paired with black strappy stiletto high-heels. She has long, wavy dark hair with full bangs and subtle, elegant makeup. The mood is glamorous and luxurious. The subject is sitting sideways on a wide, light-wood stair step. Her left leg is crossed over her right knee, clearly showcasing the stiletto sandals. Her right hand (holding a dark smartphone) is lifted near her face, actively taking a high-angle selfie. She is looking directly at the phone camera. The setting is a modern, minimalist luxury home interior. The background features a wide, symmetrical staircase made of light-colored wood (e.g., maple or oak) with treads that are individually backlit by warm linear LED lights. Clear glass railings secured by black metal posts frame the subject. Aesthetic: Architectural, contemporary design, clean lines. Camera: Full-Body Portrait Shot, slightly low angle (worm's-eye view) to emphasize her height and the structure of the staircase, 85mm prime lens, shallow DoF, with the subject in crisp focus and the background elements (railings, far steps) slightly softened. Composition: The subject is perfectly centered within the frame. Lighting: Soft, diffused studio light (softbox) from the front-left, providing flattering, smooth illumination on her face and skin. Dramatic, warm (3000K) linear under-lighting built directly into the wooden stair treads, creating horizontal lines of glow that define the background. Medium contrast, well-defined shadows that still preserve detail in the black dress. Perfectly exposed, emphasizing the sheen of the satin material.
