Read an interesting article on what makes something a Regency. For instance, Emma can be Clueless. Regency? As if!
But, if detail is not paid to fashion, manners, and décor, it is not a Regency.
All too true. It's really in the details that make it an historical an historical. It's language, rules, etiquette. Without that crucial difference, you can take a story like Emma and turn it into a movie like Clueless.
I like this whole paragraph, but let's face it, the last sentence says it all and is one of the prime reasons (but not the) that I loathe that version.
The Bennet sisters in Pride and Prejudice are all clad in very simple pastels signaling they are marriageable but not wealthy. Mr. Darcy's aunt is clad in a blend of late Georgian and Regency, expressing her independence and dominance in both character and social position. Persuasion's Anne Elliot, now a spinster with no expectations, fortune, or hope of marriage, wears exactly what she pleases in the way of color. The various members of her family dress according to their age and station in life. In the 2005 version of Pride and Prejudice, director Joe Wright’s muddled approach to costume is so deplorable, it is the perfect example of what a Regency is not.
