There’s a popular dance in the modern English country dance community which I often cite as a dance that has a Regency “feel” to it, albeit with some quibbles about the details. That doesn’t make it a Regency-era dance (it’s decades too early), but it’s an earlier version of the same style popular in the Regency and uses some figures that remained popular into the first quarter of the nineteenth century. That makes it a reasonable dance to use for a Regency/Jane Austen event in the absence of dancers and/or a caller who can handle dancing in actual period style. But it doesn’t make the modern dance a good historical reconstruction even for its own era (leaving aside how close that is or isn’t to the Regency era) without some major fixing up.
