Well, there's already a topic about it here on the 2nd page: http://forum.square-enix.com/ffxiv/t...o-te-And-Au-Ra

I know why people want this, but personally I disagree. The tail doesn't show on the ghost costume precisely because it's so voluminous, so it makes sense. For anything remotely fitted, it seems ridiculous.

But, I agree it would be nice if for gimmicky costumes like the chocobo/moogle/reindeer suits we could hide them, but for actual gear, I don't like the idea myself.
