Recycled costumes?
Did anyone else notice that the greenish-blue patterned dress Fanny wears during the play rehearsal scene (and which Mrs. Norris wears at the very beginning) seems to look very much like the one Sally Hemings wears in Jefferson in Paris (the one she makes from the fabric Mrs. Cosway helps Jefferson pick out)? Fanny's dress can be seen on You Tube (approximately half an hour into the program) and below is a link to a picture of Sally's dress:

Maria's pink and white dress from the scene where her father asks her if she is certain she wants to marry Rushworth also looks a lot like Kate Winslet's picnic dress from Sense and Sensibility. As already noted on IMDB, Tom wears Sir Walter Elliott's coat from Persuasion (1995). Maybe the costume department was too busy raiding the Cosprop vaults to bother about historical accuracy, since there seems to be an anachronistic mish-mash of styles from the 1780s, 1790s, and early 1800s in any given scene.
