Are you living in the 12th century and don't know what you should be wearing? Take a look at the 12th Century Clothing List on Yahoo Groups for discussion of period garb.
From the group description:
This group is intended as forum to connect people who are interested in 12th Century medieval clothing. We aim to share and expand knowledge about the clothing and accessories worn in Europe between AD 1100-1200 by both the aristocracy and the working classes. While much of the research up to the present has focused on either the high court fashions of French and English women (particularly the elusive "bliaut") or that worn by the armies of the Outremer, we are constantly trying to improve our understanding of what was worn by men & women in the rest of Europe during this time period.
