I plan to play a Battlemage build and thought that I'd put together some apparel for my potential character just for show, also since Blades are one of my favorite factions.

You can find heavy armor versions of the robe in the chest at the Cloud Ruler Temple armory, along with Blades circlets which are set to be clothing items. so now you might as well be able to play as Professor Chaos from South Park, huehue Those circlets you find in the chest take up the Amulet slot and can be placed in a companion's inventory, while one sample take up the tail slot. Should you be bothered by the slight penalty to spell effectivenes when wearing armor, you can find unenchanted clothing versions in a sack in the Testinghall.
You can also find a uniquely enchanted version of the robe inside a display case in Martin's room.


Known issues:
When you load a save with the circlet equipped, it will be invisible until you re-equip it.

Credits to AlienSlof since I borrowed the cut-out pauldrons from one of her revealing male armor replacers before I was able to figure out how to edit a mesh in blender and import it to NifSkope.
