User blog:Wizard Robin/Costumes

My roommate promised me that if I could make him a costume based off the Merlin costume he would wear it. I am going to use pleather for the jaket and belt, that much I know. I'm just trying to figure out the fabric to use for the shirt and the scarf around his neck. My roommate wants the blue shirt/red scarf combination. Any help or ideas would be great.

I know back then they would have mainly wool and cotton material, but I am not above using blends of fabric, like a cotton/polyester blend. I just want it to look good.

Any help would be great.
