I found this fantastic resource online, a guide to women's regency fashions. It's a really interesting website on fashion history.
This blew me away... my Elizabeth Bennett dress was featured on The New Yorker's Books blog Literary Halloween post!
THE BOOKS ARE ALIVE! RETURNS - it's #6 in the slideshow. I'm a big New Yorker fan, so that's a huge *wow* for me. The costumes in the slideshow are all from the delightful Literary Halloween Costumes flickr group.
