Armor sets and looks - guilds and factions

Hi, I am an aesthetic player, and for me looks >stats. Im wondering how many different armors can we get and how do they look like.

1. Rags, clothes, whatever the vendor in Greyshaft Has - ok
2. Gravediggers guild - do you get an Armor from them to be looking like every other gravedigger you swe? With one metal shoulderguard?
3. Bounty Hunter guild - their armor Has an awesome 15% to melee, but the looks... Its cool, but its more of a clothing look, not Armor.
4. Smugglers - do they even have a set? Couldnt find any info.

Extra: in next acts, do those guilds have their upgraded/stronger versions of those armors?

5. Free Hunters - you can get the overall idea of what faction Armor you can expect. My question is - can you eventually work up to the version with fur, like their leader has?
6. How many variations of Armor do the Knights have?

Currently still in act1, despite countless hours in the game. Lvl 14, have a few legendary weapons, found heaps of ability/skill potions, and rocking a reinforced Hunters Armor.

Also, if you have statblocks or pictures of those later sets, that would be awesome
