Minecraft wiki entry for Building_a_metropolis, associated text: Clothes Store Make a lot of leather armor, dye it custom colors, and put it on armor stands for players to trade. You could arrange by color, arrange it in outfits, or whatever other way you come up with. You can also sell other kinds of armor. To look extra authentic, either put the armor on armor stands, or add "models" by luring a skeleton or zombie into a glass case and give it the armor. If you are in creative mode, you can put a human head on as well to make them look more like humans. (If you are using the latter, you must give them name tags to prevent them from despawning.) Make sure that the people who are in your city can't release the monsters. For added safety, you can use barriers instead of glass.
