I am about to order a doublet for piping. When I finally found the right one, I got into trouble. I now have to choose between Heavy cotton, Melton, Doeskin and Barathea wool.

After some researching, I still can't figure out what looks best. My guess is that Melton and Barathea will be best, but I really have no idea. Is there anyone who can explain the differences and point out what would be best looking for a doublet?
