vintage vibe 80s feel

Create a realistic 1980s-inspired portrait of a young man with a vintage vibe.
Dress him in a colorful retro shirt with bold prints, light-wash jeans, white sneakers, and a classic belt.
He should be leaning against a vintage car, wearing sunglasses, with a relaxed, confident pose and natural expression.
Keep the background simple and cinematic, with warm lighting and film grain for an authentic 80s feel.
