Yves Henri Donat Mathieu Saint Laurent began his fashion career working for designer Christian Dior at the tender age of age 17. In 1962 Saint Laurent parted ways with Dior and started his own label, YSL for short, where he worked until his retirement in 1993. The company is still in full swing, however, and one of their latest must-haves is the Downtown Tote, which was introduced earlier this year. The Downtown is easy to spot because of its unusual shape and its buckles and zippers.
