A young man wears a slate-blue satin-finish button-up shirt.

"A clean, stylish lifestyle portrait of a young man with soft, voluminous dark brown curly hair styled in a tousled, textured crop with a loose fringe. He looks directly at the camera with a calm, confident, slightly serious expression, head tilted gently to the side. He stands in a relaxed pose with one hand tucked into his trouser pocket and the other hanging loosely at his side. He wears a slate-blue satin-finish button-up shirt with a spread collar, the top buttons undone and sleeves rolled to the forearms, tucked into black high-waisted tailored trousers. A black string bracelet is on one wrist and a thin white beaded bracelet on the other. The setting is a modern indoor space, a smooth white wall on the left and a brushed metallic paneled wall on the right, with a softly blurred glimpse of a bright interior with chairs and ceiling spotlights in the background. Soft, even indoor lighting, cool neutral palette of grey, blue and white, slightly faded matte film-style color grading with subtle grain, natural skin texture, minimalist fashion photography, shot on a smartphone, vertical 4:5 aspect ratio, three-quarter body framing, sharp focus on the subject."
Tips:
Add "photorealistic, soft diffused lighting, muted film tones" for a more polished look.
For a warmer mood, add "warm tungsten glow, cinematic color grading."
To emphasize the outfit, add "smooth satin shirt texture, crisp tailored trousers."
