The iris note is very 'faceted'. I've been working on it for years. It's very difficult if you work with iris not to be overly rooty, not to overdo an earthy feeling or get too powdery. Like when you look at an Impressionist painting, it's about how you contrast the shadows and the light so that something appears more airy and more delightful than it otherwise might.
What I will say is that this fragrance is composed of traditional ingredients of a high-end quality, yet the result is something innovative, something that wasn't there before.
