"base item and projected item are equippable by the same class or job"

[SpookyGhost]

The question is:

I have an Allagen body, I glamor it to my PLD myth body. All is good on my PLD and what not. What if now I switch to my warrior. Can I no longer use my Allagen body because it has the appearance of a PLD body.

Since Glamours can be saved specifically to Gear Sets, I imagine they're set on that equipment per job. Could be wrong, but that's what it seems like.
