Italian fashion house Prada was founded by Mario Prada in 1913. In collaboration with his brother Martino. A set of numbered Exclusive "artisan fragrances" was first offered by Prada at their boutiques and select department stores in 2003. Each scent focused on a single note—Iris, Orange Flower, Tuberose, Violet, etc. Additions to this line were made again in 2007 and 2010. Prada's first mass market fragrance offering, Prada Eau de Parfum, was released in 2004. The Prada "Ephemeral Infusion" line, which highlighted some of the notes from the Prada Exclusive line and featured more costly ingredients, was introduced in 2007 with Infusion d'Iris.
