Most of my characters are vampire mages, and while vampire gear from Dawnguard looks great, it is classified as light armor and that breaks my mage armor perks, so I created unarmored versions of Vampire Royal Armor, regular Vampire Armor, Gauntlets, Boots, Serana's Hood and Vampire Robes. They are all craftable at any forge, no perks required as they are just plain unenchanted clothing.

I also added craftable Black Robes and Hooded Black Robes for convenience as they look great with Vampire Gauntlets and Boots. Also Vampire Hood and Hooded Black Robes can be worn with circlets.

Version for Skyrim Special Edition can be found here - http://www.nexusmods.com/skyrimspecialedition/mods/2966/?

All are enchantable.
