I just wanted to post a couple of great links. First one to Jane Austen’s World, she has this list there with so many Regency links! About everything you could think of! Here it is: Social Customs During the Regency Era
The other one is to the Jane Austen Movie Gown Page. The title of this page really says what it is. Very good site with most dresses from most of the adaptations, and with plenty of detailed views.
Have fun browsing!
