The Little Corset Book by Bonnie Holt Ambrose (1999, Paperback, Reprint)

This is a nifty little guide, more a detailed pamphlet than a book. It is wonderful for the fact that it gives instructions for making patterns for several corsets, with instructions on how to change the sizing. This is very useful for those needing period clothing and for those who just want a better, sexier corset to go with a costume or formal wear. There are more detailed guides out there, but this is perfect for anyone who is only going to make these on a small scale.
