Luxury Casual Fashion Duo | Candid Celebrity Street Style ✨

Create an ultra-realistic, high-resolution candid fashion photograph of a stylish young man and a young woman walking together outside a modern luxury building with large glass windows and elegant silver metal railings. The young man stands on the left side of the frame. He has thick, naturally wavy dark hair, a clean-shaven face, and a relaxed expression while looking slightly to his left. He wears a premium beige knitted sweater with dark brown ribbed trim and elegant vintage-style lettering across the chest, paired with light blue denim jeans. A black smartwatch is visible on his wrist, and one hand rests casually in his jeans pocket. The young woman stands beside him on the right, smiling with a cheerful, surprised expression while looking slightly upward. She has long, straight brown hair with a natural center part. She wears a fitted chocolate-brown long-sleeve top with a flattering draped crossover neckline and ruched detailing across the torso, paired with light blue high-waisted jeans. She casually holds a smartphone with white wired earphones in one hand. The setting features a modern glass-fronted building, reflective turquoise-tinted windows, automatic glass doors, polished flooring, and minimalist metal railings. Use soft natural daylight, realistic skin tones, detailed knitwear texture, natural hair strands, accurate denim fabric, and a candid paparazzi-style photography aesthetic. Vertical 9:16 composition, medium full-body framing, subjects positioned side by side, realistic facial expressions, subtle background blur, professional DSLR photography, 50mm lens, sharp focus, natural color grading, photorealistic 4K quality. Preserve natural human proportions and the spontaneous walking moment. Avoid distorted hands, artificial skin smoothing, exaggerated expressions, and cartoon effects. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
