As an art and design student with a strong interest in historical fashion and costumen I have found this book both interesting and helpful. It contains a modest collection of patterns with progress through the history of the corset. This patterns are displayed on grids at 50% making them easy to scale up or simply enlarge with a photocopier (as suggested by salen). This is a huge advantage over books such as Norah Waugh were the scaling up of patterns is much much more difficult and time consuming.
There are some great basic tips on things such as cording, flossing, creating eyelets as well as a list of suppliers. However there is little information on the more detailed aspects of making up the corsets (other than two "projects" at the end of the book,which at lesat make some other patterns more straightforward).
There are photographs of each corset though many are from museum collections so are not always perfect, but coupled with clear illustrations demonstrating both the rear and the front of the corset give a clear idea of how each should look.
This is a great buy for anyone wanting to learn more about corset patterns throughout history and who is happy to make replicas of historical corsets. Though those who are looking to make fitted corsets from scratch may not find there answers here (try the book "Waisted Efforts" for that) however they may find some interesting design ideas.
