From time to time I get a wild hair up my butt and go racing off after yet another historical clothing style. This is my page of notes on sites I’ve found useful.

Vikings
Kaftans – A review of the two types of coats worn by male Vikings, with references to garments from related cultures.
China
Pre-20th century Chinese clothing offers its own research challenges. There’s plenty of material available, but due to a lack of interest, almost none of it is in English apart from studies of dragon robes. (You can learn anything you want about Qing dragon robes.) On top of that, China, like much of Europe, has romanticized the clothes of past eras, leading to movie depictions of questionable accuracy and–more problematically–modernized versions of historical garments that are worn as ceremonial garb. It’s tough to find details about historical construction when the same garments are still being made today to “traditional” patterns that probably don’t date back farther than the 1800’s.
