After an all-black outfit, my second go-to travel outfit is an all grey one (it used to be an all white outfit but I found it gravely impractical after a tragic soup accident in an airport lounge). Grey is a casual switch up from an polished all black outfit, and there's something quite "fair isle" about the color that makes it perfect for winter.
