c. 1300, dudde "cloak, mantle," later, in plural, "clothes," especially "ragged clothing" (1560s), of uncertain origin but probably from an unrecorded Old English word. Compare Old Norse duði, Low German dudel. Related: Duddery "place where rags are kept for sale" (1550s); dudman "scarecrow, man made of rags" (1670s); duddy "ragged, tattered" (1725).
