I have been searching in hopes to find some vampire like clothing/maybe robes for my pure mage in prep for Dawnguard. He will be using Master Destruction Robes soon and unfortunately right now is wearing arch mage robes, i'm not concerned with how he looks as of right now. I have a gut feeling that the only new vampire gear added with Dawnguard will be armor (Light or Heavy), Lord Harkon in the trailer is clearly wearing armor of some type (Light my guess).

I don't really see Bethesda throwing in anything for the pure mages on the vampire side of things, I am not a beta tester, it just something I am rolling with. I am half attempted to respecing my perks via with a mod to Light Armor from Alteration just because I think the coolest armor will be Light Armor in Dawnguard.

Anyway here is my mindset on cool clothing for pure mage vampires, not that I expect to find anything like this or even needs to be a robe.

Hah I dunno maybe just a reskin of Fine Clothes, then I can put the master destruction robe stats over to that.
