40 Years of Calvin Klein

Eva Mendes

The art and entertainment worlds came together to fete the iconic American fashion house's 40th anniversary. The one-of-a-kind event was held in a space that hasn't been open to the public in decades-on an elevated railroad structure in the West 30s-known as the High Line, which will soon become a park for New Yorkers. "It's a very chic, unpretentious way to celebrate the evening," said Secret Obsession face Eva Mendes, who wore a dress by Calvin Klein designer Francisco Costa. "Being part of such an iconic brand is a dream."

owes more to Calvin Klein than simply a few stunning red-carpet looks-the actress was wearing a Francisco Costa design when she first met boyfriend Liev Schreiber. "I'm sure the dress played a part [in the romance]. It was very feminine, but like all of his designs, the lines very were clean and sharp."
