Naysayers need to realise that this discussion is twofold.
Point 1: Not enough variety. Scratch that. There weren't that many pieces by themselves, forget variety. We had Morrigans robes, Mage Circle Robes, and Furry robes. Contrast that to the numerous plate armour sets in the game. Juggernaut, Warden-Commander, Cailan's Armour, Templar's Outfit - etc. Let's not even get started on the weapons. Mages had a total of what 3 unique staves? Whereas plate wearers got cool weapons like Asala and Topsiders' Honour - that came with their own cool backstory!
To salt the wounds, DLCs offered Starfang, Bloodblight, and more plate armour (!!!). It's like the devs couldn't even be bothered to add a little something for their spirit healers, blood mages and shapeshifters (I'm sure they're out there ;P).
I won't even touch the subject of leather gear... Wade's armour, Felon's Coat, Dalish armour - all a testament to a fortune the dye sellers make in Thedas.
Point 2: Actual designs of the outfits. Here things get murky. I see people posting a lot of things they'd like - and who I am to say what's right and what's not? Taste is subjective. What we can all agree on (I hope) is varied designs would be a pleasant thing. I'm fine with mages in their (matronly IMO) Circle garb and their lovely ornate lampshade hats. Some people like them, and that's fine.
What is not okay is when Reaper's Vestments look basically like Chasind robes. Which is what I hope isn't the case in DA2.
The idea behind an RPG is that you're going on a quest, and on your way, you acquire items of mythic proportions (Legion of the Dead set, for instance) to achieve your heroic ends.
For those saying that travelling clothes should not be fancy - yes, I agree. It's inane for a new mage to have ancient, powerful attire. Starting gear can look drab, or ordinary. Epic gear needs to have that wow factor to it. That's the beauty of progression in an RPG.
If the technology were such that we could show our raiments going through the motions of wear and tear, I would sign up immediately. But we're not there yet where our Grey Wardens have to go to the local laundromat to get their [Minrathous Magisters' Garments] cleaned.
The bottom line is, if an item is named Tevinter Robes, then it better look somewhat impressive because Mages are the cream of the crop in Tevinter society.
