This particular find comes from Bethany L. and her mother, Barbara. Beth was doing a project for school on the Regency era and the topic of style must have come up. They found this wonderful page as a resource and felt it should be more widely known. So, if you are curious about men and women's fashion during the very late 1700s to early 1800s and want a nice, succinct overview on it, check out: Regency Era: Fashion History, Culture and Lifestyle
A big thank you to Bethany and her mom for bringing it to our attention!
