One way to fix is to make all items places into the Glamour Dresser keep only their level rules for glamouring, items placed in the armoire would still keep their job/class and level rules for glamouring; then restrict "artifact" gear from being able to go into the glamour dresser while making all "artifact" storable in the armoire.
done.
I will point out there you can "try on" anything. It doesn't stop you from trying on items unless there is a racial or gender restriction. So, pretty sure you can turn off the role restriction a lot easier.

Unpopular opinion: I don't care for class restrictions in general on gear. So what if someone can equip gear that boosts the wrongs stats!? If they do not know what stats to boost, they aren't going to be great at their job when forced to wear specific gear either. I do understand that PLD armor should only be worn my a PLD, and so on, but that is artifact gear... thematically it is very different.
