Photorealistic Street-Style Portrait with Appearance Preservation

Strictly preserve the girl's appearance from reference 1:1: facial features and proportions, age, skin tone, eye color, and hair color. No idealization. Photorealistic street-style portrait, 9:16 format. The girl stands beside a classic city facade, body slightly turned, face looking at the camera, gaze to the side. In one hand she holds a white coffee cup; the other is in her skirt pocket. Hair is gathered into a neat low bun, with thin strands framing the face. Clear oval glasses in a metal frame and large gold hoop earrings. Preppy casual look: an oversized beige Polo Ralph Lauren sweatshirt with the Polo Bear and the text "1979 NEW YORK," a light blue shirt with thin white stripes underneath, and a short cream pleated skirt. A large dark brown leather bag over her shoulder. Dark facade with tall windows and architectural reflections, autumn leaves nearby. Soft daylight, a calm beige, blue, and brown palette, natural textures, a light film effect, and a Pinterest aesthetic.
