Well, absolutely the best link for authenticity would be to your local Public Library, and the book "Costume 1066-1990s" by John Peacock, although it concentrates almost entirely only on the British Isles... Otherwise, look for the following terms: Breeches Tunic Houppelande Tabard Or do a search for "Period Costume" Cheers!
