Frankly, the stuff is simply gorgeous. I rate it alongside Iris Silver Mist and Iris Bleu Gris as one of the finest iris scents I've tried. It's rich and deep, yet not heavy, beautifully blended, and supremely dignified. I heartily recommend sampling it, as it is one of the most sophisticated floral scents I can recall. Here is my review from the Basenotes Directory:
"Stunning. Iris Poudre is at once beautifully soft, yet cool and austere. Magnolia, jasmine and iris meet in an accord whose whole is far greater then the mere sum of its parts. Meanwhile, the powder half of Iris Poudre is rich, and almost creamy, the aldehydes neither too "pretty" or too harsh.Hope that helps!
I can't rave wildly enough about the deft integration of the iris here. All of its rough edges are smoothed over, but this iris still has teeth. The development is marvelous, too, with sandalwood, powdery musk, and just a touch of vanilla sweetness underneath the lingering floral accord. Not merely exqisite, but the first iris scent I've been able to wear comfortably."
