Signature pair: Agarwood (Oud) and Saffron
Differences come from accords and community votes on longevity and sillage.
The main accords of Armani Eau de Nuit Oud are warm spicy and rose. It opens with Cardamom and Pink Pepper, reveals Rose and Iris at its heart, and dries down to Agarwood (Oud) and Saffron. It lasts long and projects strongly; people reach for it in autumn and winter, mostly in the evening.
