Vintage dancing is an authentic recreation of historical dance styles. Usually in a big hall with a live band and we dress formally, with some in historical attire. For more info, you could google Gaskell Ball and PEERS which are the two I've attended. We dance waltzes, galop, schottische, polka and many more including line dances such as Strip the Willow.
But for what it's worth, I can also dance like a flapper 😉
