I don't want to be pushy but broadcloth is not necessary the best choice. Cotton is period. A Viking made a stir in Paris in the 900 wearing a multi colored cape of cotton. We have period bestiaries showing pictures of the little sheep growing off the cotton plant. But I wonder about the fineness and tightness of weave of Broad clothe. If you are over at Wal Mart go look at the one dollar and two dollar Poly cottons. 100% cotton will wrinkle and the Poly-cotton won't. We don't want to use !00% poly because it is too hot. It doesn't breath. Poly-cotton breaths and keeps its color. Often you can find interesting textures in the one and two dollar bins, Look for bright colors. Contrast is period. You will find pastels and matching shading in period Japan, but most of Europe liked strong contrast. What is that story about Charlemagne wearing green red and blue? Stay away from too shiny fabric.. Go look at the real silks and then look for their match. If you want to know about a color go ask Mistress Stella. By the way we are studying what people in Middle Ages thought should of been. Read a period Romance and you will find some wonderful descriptions of clothes. If you believe what they wrote everyone had bright colors on. There are two things that really spotlights that you are new, Light pastel blue  and fading ill fitting  black clothing. Many newcomers first attempt to be period is blue cotton tunic. Most of us have a thing for black. If you are going to wear black makes sure it is really black and it is a good idea to put a contrast color with it and try to make the garment with shape.
