Vintage portrait of a young woman.

Create a realistic vintage portrait of a young woman sitting cross-legged on a bookstore floor, surrounded by stacks of books. She wears a white turtleneck, denim overalls, round black glasses, and long straight dark hair. She reads an open book with a calm expression. Warm moody lighting, muted colors, nostalgic film grain, candid photography, authentic bookstore atmosphere, cinematic 90s aesthetic.
