Motley is the traditional costume of the court jester, fool, or the harlequin character in commedia dell’arte. The harlequin wears a patchwork of red, green and blue diamonds that is still[citation needed] a fashion motif.

The word motley is described in the Oxford English Dictionary as a cognate of medley, although the unrelated mottled has also contributed to the meaning. The word is most commonly used as an adjective or noun, but is also seen as a verb and adverb. When used as a noun, it can mean “a varied mixture”. As an adjective, it is generally disparaging: a motley collection is an uninspiring pile of stuff, as in the cliché motley crew.
