Photoreal B&W Fashion Photo in European Arcade

Photoreal black-and-white fashion photograph in a grand European shopping arcade with arched glass roof and patterned marble/mosaic floor. A chic young woman in a sleek black evening dress with a thigh-high slit bends gracefully to slip on a stiletto heel; one shoulder strap slightly off the shoulder; head tilted down; soft hair across her cheek. Vertical full-body mid shot, subject centered in foreground; glossy floor reflections visible. Background: softly out-of-focus shoppers and two large luxury boutique windows; storefront signage present but intentionally blurred and unreadable (no legible logos). Lighting: bright diffused skylight from above, clean shadows, rich tonal separation; real skin micro-texture; crisp fabric edges. Rendering: strict monochrome (no color tint), fine film grain, Leica-style micro-contrast. Camera: 50mm, f/2.8, 1/250, ISO 200, eye-level. Negative prompt: color, sepia, cyan tint, illustration, CGI, plastic skin, over-smooth skin, motion blur on subject, blown highlights, HDR halos, posterization, extra limbs, duplicate legs, readable text or logos, watermark
