Armoire should ideally permit...

1. All Job sets.
2. Mog Station Store items.
3. Maybe even glamour items gotten from special enemies and FATEs, like quest rewards (Sophist Attire, Wayfarer's Attire, Scion Rogue/Adventurer Attire, the Scorpion Harness or Strider Boots from Eureka)...

Reserve the Dresser for crafted and instance-obtained pieces.
