I wanted to use the Greybeard clothing for my mage character and as it turns out Bethesda made it so the clothes don't show up in your inventory even if you add them with the console. So I made them show up, and I made them craftable. 

You will find the clothing in the Misc section of the forge list. They don't require any smithing perks and can be made at level 1 smithing. For the robes you'll need 5 leather strips, 3 leather, 2 linen wraps, and 1 silver ingot. For the hood and boots you'll need 1 leather and 2 leather strips.

I have no relation to the mod author who added these robes to vanilla skyrim, however as it seems he has not ported the mod over to special edition, I figured I would do it. I also did not just take his mod and reupload it to the remastered nexus, I started from scratch and made a new .esp file.
