Curious Perfume by Britney Spears, Released in 2004, Curious is a soft, romantic fragrance for the woman open to all of life’s rich experiences. The fragrance begins strongly with the heady scent of Louisiana magnolia. Seductive and mildly sweet, it is both charming and intoxicating. Smooth vanilla lends another layer of sweetness, with a milky soft finish. A subtle musk drifts behind, forming a lingering base note evoking mischief and, of course, curiosity.
