Custom Name Dual-Tone Shirt Portrait

"A realistic 4k cinematic portrait of a handsome 24-year-old South Asian man with a well-groomed full beard and voluminous, perfectly styled dark hair. He is wearing a unique split-color button-up shirt where the right half is solid white and the left half is solid black. The white side features the text 'SAIM' printed in bold black letters on the chest, and the black side has a subtle dark Nike tick logo. He is wearing black aviator sunglasses, a black wristwatch, and matching black cargo pants. He is standing outdoors with his hands in his pockets, looking straight toward the camera with a confident expression. The background is a softly blurred modern cityscape or tall buildings with gentle evening lights (bokeh effect). Crisp details, natural lighting, urban street fashion photography style."
