Anyways, there are a few good books you can pick up at your local Barnes and Noble.

One notable book is "Dress in Anglo-Saxon England" by Gale R. Owen. It is decently written and seperates male and female, further seperating by era.

I, like you, found nothing of much substance on the web. But I did do a search for the aforementioned book and author and came up with page that may or may not be useful:



It's not much compared to owning a book, but it may be enough to get you through, although I didn't see alot concerning dress of the poor.

When you get there (the pictures are worthless) Click on clothing and scroll down, it has Men and Woman costume, seperated by Pagan / Christian, with a few pages on each.
