Do you ever think the moogle attire will return?

[Sakuraluna]

Moogle suits paws and feet are closest to cat that we will ever get.

No, it's not. If you want to be a cat, then use a fantasia and change to a miqo'te. No use getting yourself bent out of shape trying to base your in game identity around an exclusive item that's not available to you. If it comes available again one day then you can pick it up then, but if it doesn't it doesn't. ( I don't think it should but that's beside the point.) It most likely won't come back at least not anytime soon so why not just find something else to aim for and move on?
