Korean Exclusive Dress from 2017... when?

[Kemiko]

As stated earlier in this topic, these sorts of items aren't handled by the main team and instead by teams running localized versions of the game in China/Korea. Whatever licensing involved in the items released there are likely the gate keeping them from being released to the wider FFXIV audience and why these items, if released to the wider audience, take time to get into our hands. The fact this particular dress, as much as I like it and would pay to own it, hasn't yet been released likely indicates that the gate on it is more strict than those released already.

IIRC, there's also a jacket that released a long time ago and still hasn't been made available too.
