Paris Hilton Siren perfume emanates a distinct feeling of casual sophistication perfect for any time of day. Introduced by celebrity heiress Paris Hilton in 2009, Siren is composed of a perfect balance of mandarin, water lily, frangipani, coconut orchid, apricot nectar and sandalwood, among other notes. It's an attention-drawing fragrance that works just as well for hanging out with friends as it does for coffee with a special someone.
