Giorgio Armani Si Eau de Parfum 30ml Spray by Giorgio Armani for WomenThe composition of perfumes is a fascinating study. Every fragrance contains a blend of top notes, middle notes, and base notes. The top notes hit almost immediately after applying a perfume, but they last mere moments. Middle notes replace the top notes, staying about one hour after application. Following the fade of the middle notes, the base notes take over. These heady scents will last for several hours, and they generally make the most memorable impression. Si by Giorgio Armani features a rich combination of top, middle, and base notes. The top notes of Giorgio Armani Si perfume include Italian blackberries and white cedar wood. The middle notes include cassis, nectar, rose de mai, and freesia. Base notes round out the scent with chypre accord, musky wood, orcanox, and vanilla patchouli.
