I come from a Renassaince reenacting background where we encourage spectators to dress up. It not only pulls them closer to actual participation but the longer they do it the more accurate they want to be and the more they want to learn about the history. I know lots of people that started out as dressed up spectators and eventually became full members of the Faire. We should always encourage a love of history!
