Fashion souls isn't a thing here. Each biome will give you a new armor option that is superior to the previous option. It is advised to get and upgrade new armor asap once it's available. I would love to see more options and even more specific set bonuses or perks in order to keep armor relevant. A set that is good for poison, aka thief set, could remain useful in the swamps, ect. As of now, you end up in the padded armor because it's just better and in it, the swamp, mountains, black forest and meadows becomes trivial.
