Dyeable (NPC outfits are not dyeable), and 2. Not past event items (FFXIII outfits are past event). Granted, they could be $15 USD, too, but $18 USD for a non-regional outfit is a first-time thing; we will have to see if the next non-NPC outfit is also $18 USD, or if they just go back to $15 USD.
The Maid and Butler outfits are both non-chinese exclusive, and are $18. There is also the Fuga outfit, which is only 2 pieces, also at $18. So no, it's not a chinese exclusive reason,

You'll also notice only the $18 outfits have the set bonuses.
