I actually compiled T3 armors for this purpose, trying to give each of my 10 Inquisitors a unique look (hasn't worked out)... There actually aren't too many unique looking (T3) armors. Amongst the first three I've listed there are some very minor differences, but for all intents and purposes, its the same look across all three classes.

I'll post images but most of the inquisitors aren't mine, fyi. Also just note that these are all probably crafted and colors and arm/leg armor can vary.

1. (Superior/Sturdy) Battlemaster/Prowler/Battlemage Mail
2. (Superior/Sturdy) Battlemaster/Prowler/Battlemage Armor
3. (Superior/Sturdy) Battlemaster/Prowler/Battlemage Coat
4. Superb (Heavy/Medium/Light) Armor of the Dragon
5. Templar Armor [Heavy]* My Inquisitor
6. Legion of the Dead Armor [Heavy]**
7. Dalish Warrior Armor [Heavy] Female Ignore the fact that it's worn by a mage. I've never come across the male version, so I have no idea what it looks like...
8. Dalish Scout Armor [Medium] Male Female Ignore the fact that it's a mage wearing it.
9. Keeper Robe [Light] Male Female I'm told the version PC version is the same as what Solas is wearing.
10. Formal Attire [Light]

*Templar armor actually differs for each class in looks (use Silverite to remove class restrictions). Rogue Mage While Dorian and Cole are pictured, the style doesn't change for these for the PC.

**I have little idea if there are different versions of Legion of the Dead armor for different classes... If anyone knows if there is, I'd be interested in seeing it!
