Preparation for a “Medieval Market” event

I just got more information about the medieval market that I may attend.  The time period is 11th-12th century in Germany right near the French border. I’ll have to make a simple costume. Any suggestions? Are there any photos to consult? I did find:

I’m to bring my own stand for my herbal soaps, and my biggest worry is some kind of roof in case of rain. We can’t use plastic, of course, so I could use some ideas on that, too.

I think these patterns look fine, especially for someone just beginning.
