I think Iris Oriental (Formally known as Iris Taizo) may be an attempt to steer away from the stereotypical presentations of iris.
This one opens with a juicy raw cut carrot accord, the kind of carrot you get in Iris Silver Mist, without the vapory feel. As it settles, the texture seems to go smooth, balmy and powdery at the same time. Vanilla and honey add to the natural sweetness in well-measured moderation. Incense, wood and resin, give Iris Oriental a more well-rounded character. On the whole, this feels like an iris amber.
I actually like how this one manages to refrain from smelling like cosmetics powder.
I think it is safe to say that Iris Oriental is like a Cuir d'Iris without the leather, with amp-up iris and powder. Great for someone who prefers a straight-up rich and rooty iris scent, and is a little jaded by the usual iris soliflore.
