What kind of material goes into making a silk or satin kimono robe?

Just walk into any fabric store or dept store that has a fabric dept and tell them you want to look at silk and satin material for a neglige. Then pick out the color or print you like and always purchase a little more than you need, in case of mistakes, or if it is at the end of the bolt and there are only a couple of yard left, buy them, you can always make something with the leftovers if not needed. But better not to have them run out, and then need some more.
