I've used the Norris book for Medieval Costume before and I love it, and this one is that much more. In addition to plates and figures, that show the costumes in period illustrations, the book is organized by reigns, and includes sections on orders of chivalry, headdresses, hats, shoes, jewelry, and discussions of usage of every part of the costume. The biggest danger is allowing Norris to be your only source, just because it has everything. Enjoy, I have already spent several evenings just perusing the book, and I have several plans for costumes.
