I think I just figured out how to make your mage followers equip better robes without using pickpoket(to take out their original gear).
You see, when playing with my paladin, I normally use llia as my follower(a very powerful frost mage, you can find her in an abandoned fort just south of Riften). She starts using normal mage hooded hobes. Since she also like to use a one handed weapon and fight in a spell-sword style i tried giving her some armor, but she only equiped the gauntlets and the boots.
Just a few minutes ago I was in a Dragon Priest dungeon, after killing the Dragon priest I noticed that I was carring too much stuff so I gave her some of my loot , and when i gaved her the Dragon Priest mask she equiped it(she was refusing to equip even circlets before that). Since she wasn't using a hood(it was just a hooded robe) she got naked But by doing so I was able to get her wearing armor, since she wasn't using any gear on her "body part". I wondered if she would equip robes as well and she did! Now you can finally give your mage follower the Arch mage robes.
PS: I'm not sure if this will work with the students from the College, since they are wearing hoods AND robes, not just hooded robes. Still, It's a fine discovery, right?
PS: I know, my english sucks, sorry for that.
Thx for the reply. About the bad english: You see, I never made any kind of "english class"(we have english classes at school but, let's just say that the only thing they teach you is how to use the "to be" verb) so basically all my english was learned by playing video games and/or wathing movies. At least you got what I was trying to say
Dude, your fucking amazing! Thanks alot man. I always knew there was a way, just couldn't figure the pattern out.
PS
I also wanted to add in that now I can make my Warrior Followers wear robes with me, I like the idea of questing around like that. I gives me the feel of a sense of realism when you are rangers and not some Hulking Badasses roaming the wilds of Skyrim in End Game gear.
