From the context, which of the following best defines the word “motley”?

It was about dusk, one evening during the supreme madness of the Carnival season, that I encountered my friend. He met me with excessive warmth because he had been drinking much. The man wore motley. He had on a tight-fitting, multi-colored suit and on his head was a conical cap with bells. I was so happy to see him that I thought I would never stop shaking his hand.
