Renaissance style shirts?

My friends and I plan to go to a Renaissance Festival next month and we wanted to dress up when we go. Currently my friend and I both sewed some plain, flowy skirts with drawstrings on them and mine is a maroon color. What would be a Renaissance style shirt to go along with it? I wasn't thinking anything royal, something along the lines of peasant-like. My other friend suggested a tunic tank top with holes on the chest with a cord to string them through.
