She changes from her beige knit top into an elegant urban professional outfit: a champagne silk blouse with a well-tailored dark grey casual blazer and matching high-waisted wide-leg trousers. The scene is in a modern minimalist upscale coffee shop with floor-to-ceiling windows showing a bustling city view. Dark wood tables and leather chairs furnish the interior, with a silver laptop, documents, and a steaming Americano on the table. She sits relaxed, leaning slightly back with one arm on the armrest and the other holding a coffee cup, gazing at the camera with calm, slightly languid eyes and an elegant smile. Polished formal makeup with clean base, defined brows, and mauve lipstick. Soft afternoon light enters from the side through the windows, creating delicate light transitions on her face and clothing. Natural bokeh background in earth tones, greys and warm whites, creating a serene, sophisticated urban office atmosphere."
