I am working my way through library copies of the Bridgerton series. Book 3, An Offer From A Gentleman, is a blatant Cinderella retelling, but no-one in the book mentions the similarities. So I conclude that in the Book!Bridgerton AU*, there is no Cinderella fairy tale. I'm now trying to remember if there are any fairy tales references in the books so far. Maybe they just didn't get the literary salons that produced conte de fées, and/or the Brothers Grimm.
(*) In my head all Regency romances occupy alternate universes which merely bear some resemblance to this universe's Regency period in England. Netflix!Bridgerton is a separate AU again, and also hasn't reached this story yet.
