What is the era and time period depicted in the 2015 Cinderella movie?

Disney is remarkable for depicting a “golden age” for most of the Fairy-tale epochs. Obviously pre-industrial or in the earliest stages thereof. It seems to depict the Regency or High Victorian era otherwise. though the stories are much older and attempt to emulate the Middle Ages in a romanticized sort of way.

The era of 2015’s Cinderella seems very beautiful and idealized to me. But what era does it mostly depict?.
