Create a modern luxury sports-fashion editorial. Dress the model in a premium fitted technical jacket, tailored wide-leg track trousers, minimalist sneakers, and subtle luxury accessories. Place them inside a modern glass-and-concrete athletic complex. The model stands near a large window, body turned slightly toward the city, face turned toward camera. Use morning sunlight filtered through glass, creating layered reflections. Shoot with a 50mm lens at f/3.2. Preserve realistic performance fabrics, stitching, shoe construction, skin texture, natural posture, and believable reflections. The image should resemble a high-end fashion campaign rather than fitness advertising.
