This book does not attempt to provide patterns for exact reconstructions of historical garments. However, for the theatrical person or someone just getting into more serious historical costume, this is a good place to start. The patterns provided are not traditional sized patters, so it assumes the ability to draft and adapt a basic pattern shape. The patterns given (at least for the medieval period) do give results which duplicate the basic looks of the period, without introducing some of the grevious errors of many books of this type. It's meant for practical use, so its usefulness as a research resource for documentation of a particular style is limited.
