I found a couple more fun costume books! The first one is a look at some of the historic men's clothing at the Los Angeles County Museum of Art, which is beginning to have a world-class collection of Western costume.
Then there was this book: "Costume Close-Up" by Linda Baumgarten and John Watson
This book is totally the cat's pajamas. I took a fail photo of the cover:
The book also shows the tools used for pinking and other neat things. It is a treasure!
