I go to reddit.com a lot, and found this subreddit dedicated to historical costuming. Thought some of you might be as interested in it as I am. http://www.reddit.com/r/historicalcostuming (http://www.reddit.com/r/historicalcostuming)
Any other historically accurate communities you know of?
Do you want the loosely affiliated or the strictly focused ones? There are a TON on LiveJournal and on Yahoo Groups.
all!
I am a member of a Historical Costuming group on yahoo.

Some of these are much more active than others. There are a few that I see every day that pop up on my f-list and there are a few I haven't seen anything from in years. However, if you are on LJ, take a look at these groups because sometimes, even in the archives, there might be good information. This is just a list of ones I watch. I'm sure there are a TON more.
Also, there are a lot of good blogs out there dedicated to Historical Costuming or to extant garments themselves. I only have a 100 or so of those on my google reader. ;-)
