Bring certain wears/rares into shop or store for limited time

[Ellax Brisco]

Things like kitty ears, capes etc
The rares that no one can find put into shop or store for limited time for the people who missed them by joining later

[Penguin Disco]

Yes! I know the point of the rares is that they're only available for a limited time so they can be marketed as exclusive, but it would be cool to have a "from the vault" sale every now and then where older pieces are reintroduced.
