I would say a nice tortise shell button shirt solid color, possibly a light blue or white. Tucked in but wear a undershirt that compliments the button up and leave the first two buttons undone. A pair of hip jeans, levis obviously :D a dark pair to set off the shirt. I would go for a hip nice pair of men's boots. No boots opt for a nice clean white sneaker. But boots would set off the outfit . Just my opinion. I think a man dressed like that looks good, cool, and it is a professional yet casual look. Don't forget a nice watch, and Even a nice yet acceptable ring. Again just my opinion but the company is Levis and that style would fit right in hope this helps .
Clean Levi's and neat top. Sneakers are fine, too.
Levi jeans, tucked in button up and a blazer.
