Disney’s Fairy Godmother seems to employ prestigious fashion designers. See?
Cinderella is the perfect 1950 girl; even her work clothes are this cute outfit with ballerina flats, right in style with the times. The stepsisters, on the other hand, are an exaggeration of the 1880s with their huge bustles; in fact, the whole setting of the film is pretty much late Victorian. Except for Cinderella, she gets to wear post-war haute couture.
