Alter Ego Goblin and Moogle suits

[Morovich]

I read on the Freshly Picked Vana'diel that if your wearing the Goblin/Moogle suits from the Mooblin Battle event that your alter egos would be wearing them too, I just tried it out and nothing happens, they are still in the normal gear. Has this feature been added yet or am I doing something wrong?

EDIT: If you call your adventuring fellow NPC they will be wearing the goblin suit, so that's what it's meaning.
