 Traditional-revival groups typically adopt very casual dress and traditional-revival choreographers have begun to use basic movements that were invented for Modern Western square dance forms and a few modern Western callers incorporate older dances from various traditions, such as New England or Appalachian, into their programs.Where traditional square dancing exists as a community social dance (sometimes in the form of a Barn dance or a Ceilidh) people often dress up a bit, though their clothing is not square-dance-specific.While the standard formation for a square dance is four couples in a square, there are many variations on the theme.
