I love Nordic carved with the Ebony Mail. Especially the Boots, and Gauntlets, but the carebear helm kind of sticks out like a cock in a cocktail dress. I usually just strap on a Mask anyway. Definitely the DPM, you can only wear one at a time, but with all the colors, they can mix&match with just about anything. I particularly like how the hood matches Orcish Armor, or the Master Robes (Of whatever.) I really love the trenchcoat look of Master Robes with the pannel of embroidered shirt exposed in front. Blades', and Shrouded Boots/gloves really set them off.
Honestly, I love the look of the Steel Plate set, except the helmet. One of the big reasons I go with Uthgerd more than any other Follower, when she inevitably gets Broken, you can loot her for the suit, and match it with either Yngol's or the Helmet of the Unburned.
I've always loved Bonemold (Or at least ever since Morrowind) though the helm is a little weird. In Morrowind, we had so many choices, between the different houses, and factions. All of it looked killer, and just the concept strikes me as uber cool. Chitin too, especially the Helms so I can wear Goggles. 8;|
