The company, originally known in Italy as "Prada Brothers", was founded in 1913 by Mario Prada in Milan. In 1978, Mario's granddaughter Miuccia Prada inherited what was still a leather goods business from her grandfather, and led the company's expansion into couture with an overall more bohemian style. Miu Miu is a second line of clothing, often simpler and evoking a continual image of high-end vintage items. It was followed by the Prada Sport 'Linea Rossa'. Currently Prada is considered one of the most influential clothing designers in the fashion industry. Source
