It's a look that has been sought after by some of the world's leading ladies, from style icon Jackie Onassis to actress Renee Zellweger and comedian Tina Fey, who stepped out in a navy Herrera gown at this year's Oscars. Herrera's rise to the top of the cutthroat world of fashion started in 1981, when she launched her flagship Carolina Herrera brand in New York. Today, her empire encompasses the signature fashion collection, a bridal collection, fragrances and accessories. Herrera has more than 280 stores in 104 countries and all this brings in billions of dollars.
