Here's the closest we'll ever get to an authentic Regency fashion show.
This video of actual garments of early 19th century clothing gives us a close-up view of the high styles of the day.
The high-waisted gowns, which were fashionable during the Regency period of the early 1800s, were known as the Empire look. You'll see a lot of white, which was a sign of social status since white had to be cleaned more often.
I particularly love the yellow cape and the detailing on some of the evening dresses is gorgeous.
