Rougher-looking cotton and linen-look fabric is what I've used for my Malon. I tried to use things that are typically used for Renaissance festival "peasant" clothing. Nothing too fancy or "clean" looking, she is a farmer after all! I painted the sleeve designs with soft fabric paint, and the skirt designs are strips of blue cotton sewn on.
The skirt pattern I used is out of print, but basically a full skirt with an elastic waistband, and a blouse from a Renaissance pattern (most people use a T-shirt but I wanted something a little more authentic looking).
