How to Style It
Day: over a grey tee with dark jeans and white sneakers, smart casual.
Work: pair with a white shirt, navy trousers, and black loafers. Clean, sharp, professional.
Night: layer over a black turtleneck and tailored trousers. Add boots for polish.
Special Occasion: Wear with a silk shirt, tux-style pants, and patent shoes. Keep the Fly pin for subtle flair.
