A few nice renaissance clothing images I found:
“I ride a powerful steed. Mine thirst I quench with mead. I am a powerful knight. Now mount up and fight. I wish to make thee bleed!”

A shot of one of the jousting knights. This guy was clearly the best, at least on that day. Shot at the 2009 Four Winds Renaissance Faire near Whitehouse Texas.
