Stylish Office Staircase Portrait

Reference image: uploaded photo.
A stylish cinematic portrait of a woman standing on a staircase in an office building, illuminated by warm artificial light.
Pose: leaning casually on the railing, one knee slightly bent, holding a coffee cup in one hand and a beige trench coat in the other; body language confident, slightly teasing.
Face: same woman as in the reference; soft smoky makeup, glossy lips, intense gaze behind glasses.
Hair: long voluminous curls cascading over her shoulder, shiny and thick.
Outfit: white oversized shirt half-tucked into high-waisted mini shorts with check pattern; black slim tie loosely knotted; trench coat draped over arm; beige heels.
Lighting: moody soft indoor light, cinematic shadows along the stairs.
Mood: elegant rebellion, office chic meets fashion editorial, modern femme fatale.
