The Mog Station items that go in the armoire are actually seasonal event or crossover event items that later got added to the Mog Station for people who missed the event, whereas gear that was created to be sold through the MogStation in the first place does not.

It still seems pretty arbitrary, though. It would make more sense for both to be storeable.
