Most fashionable mens head accessory?

I wanted to get a guy friend a gift for christmas.I know his into fashion and was looking at some hats the other day, what do you think would be something that looks hot on a guy?

He has boyish looks (like a young johnny depp), medium brown length hair with a longish face (think dave navarro), would a hemp beanie be cool? a clear beret? a bandana? idk.
