For what it is worth, I recommend that the armor not look like ‘too-perfectly’ a match. I would do something somewhat contrasting. Also, Robes make the helm seem more sinister, not sure why.
I would pair it with something radical like the ToEE robes in which there is a partial link via the gold lining, and a stronger grounding in the black. (All that white and gold gets nauseating to me and I want to being it out in relief). But I am not sure—I would need to see it.
If you have a lot of plat, you can buy all the robes on the AH and see how lootgen stuff looks.
