I recommend you consider looking at the works of the great artists of the time - like Da Vinci, Hans the Younger, etc. - plus read through some of the literature of the time period for telling tidbits.

I've bought a lot reference books from Dover Publications through the years. Check out http://store.doverpublications.com/fashion-and-costumes.html

Here you'll find books detailing English costume from early Middle Ages through the 16th century, plus a history of underclothing, and even clothes from Ancient times to the 20th century. Prices are very reasonable.

To view costumes online, I've used the following link quite a bit just to browse and study the plates. (Keep in mind that these plates were gathered/created during the years 1861 through 1880, so they have a "Victorian perspective" to them. But I think they're terrific and give a good look across the board at different levels of society.)

You'll find it at:

Also look at:

And for a launch pad to other links, try:
http://www.costumes.org

Great stuff - especially about colors and what dyes people had access to....

Anyway, I went to their site (www.sca.org), hit "Arts and Sciences" - the following should take you to the page of topics - pick Clothing and Costumes on the left. The links are arranged in different ways including century, which should help. They say the page is undergoing a major overhaul, so some links may not work...

Some articles are on how to make things but many are on the clothing from different cultures and time periods. Have fun reading!
