Product title: Kenneth Cole New York"Modern Tanzanite" Oval Drop Earrings
Product description: In 1982, Kenneth Cole wanted to start a company. He had an idea, a plan and a line of womens footwear. What he didnt have were the resources to get the product in front of potential customers, but he was creative, determined and ingenious., He borrowed a truck, loaded it up with samples and parked across the street from the New York Hilton, where all of the big shoe companies were showing their wares. But there was one problem; he needed a permit to park the truck. At the time, only a film company could receive a permit to park a truck in midtown Manhattan., Undaunted, Kenneth promptly changed the name of his company to Kenneth Cole Productions and applied for a permit to shoot a film entitled, "The Birth of a Shoe Company.", Three and a half days and 40,000 pairs of shoes later, Kenneth Cole Productions was off and running. Soon, the brand began to expand from its footwear roots, introducing apparel and accessories for modern men and women who wanted a part of the metropolitan dream., As the business became more successful, Kenneth knew that he could provide the best brand experience in his own retail stores. It wasnt long before the rest of the world wanted a piece of the action. Today, Kenneth is available in more than 70 countries worldwide., As the brands experience grew, so did its voice. Kenneth knew that his savvy, stylish customers had a lot on their minds. He added provocative messages to the Companys advertising and he made people things, He was, from the beginning, confident, clever, cool., KENNETH COLE IS, ITS WHATS INSIDE THAT COUNTS., Our DNA, CONFIDENT, CLEVER, COOL, AWARE
