The Sleepy Hollow Dress: Inspiration

This was my first earnest attempt at creating an authentic 18th century outfit, with all of its proper components: the chemise, the underskirt, the corset, and the bodice.
If you guys have not seen Tim Burton's Version of Sleepy Hollow, it is a gorgeous film and if that doesn't convince you enough, Johnny Depp stars in it.  He looks QUITE handsome with long hair dressed in a peacoat!
But what I loved most of all was Christina Ricci's striped gown...

So pretty!

And then I was off ordering a pattern for a robe à l’anglaise (which would be pulled up like a polonaise) from J.P. Ryan and looking up luscious striped silk fabrics.
I also got a lot of help from The Costumer's Guide to Movie Costumes (SO GREAT), since its author had also recreated this gown.  Here's the link:

First step: make a decent period corset to go underneath.
