I haven't seen anyone else mention this yet, but there's the added complication of their licensing deal with Shanda Games.
Shanda Games publish FF14 in China, and they're the ones who design and produce all of these cash shop exclusive items. SE have a reciprocal deal with them, and in turn we get the Chinese outfits a few months later in our cash shop.

Any corrective action on this, if any, will likely require negotiations with Shanda Games... and we all know how the Chinese feel about copywrite law...

SE simply pulling the outfit from the store will undoubtedly cost them money, and editing it likely isn't an option due to the above reciprocal deal.
