How to Make a Cowboy Skin in Minecraft for Free

Learn how to create a cowboy skin using only free duds from the Minecraft Marketplace. It also bears some resemblances to an archaeologist or Indiana Jones if you prefer it.
P.S. I've been told that Dr. Grant Alan's Hat was only temporarily free. If you can't get it anymore there is another hat called "Cowboy Hat" that is free and should work just fine for the outfit too.
