For glamouring, if you want to have even one Piece of it applied to your chosen Job, you need to purchase a second piece of gear, just so it doesnt interfere with the Glamour of the other classes you leveled which share the same Armor-class. At the very least, Squeenix could design those Job Armors in a way, where for example, the PLD Job Armors could be worn on any Tanking Job and so on, otherwise those will just gather dust in the armory or straight up being tossed away.
