English Women's Clothing in the Nineteenth-Century by C. Willett Cunnington (1990)

I purchased this book because I run a website dedicated to fashion accessories (specifically, opera-length gloves) and I found the book during a recent research trip to the Library of Congress. I was so impressed by the breadth of the text and the quality of the illustrations (both original and prepared for the volume) that I decided to add the book to my own library. The fact that it was published by Dover is another plus, because Dover Publications is the leading publisher in the field of historical fashion and costume.
