There is plenty of useful information in Who Wore What by Juanita Leisch. However, as she admits, the sample of photographs she worked with, although carefully dated, were not random and were not identified as to location. So her generalizations should be considered in that light. But the photos themselves are fascinating. I enjoy looking at these women, dressed up for their photos and imagining their lives.
I have collected an extensive number of photographs of men, women, and children during the Civil War period on my Pinterest Boards.
