“Kate Spade had an enviable gift for understanding exactly what women the world over wanted to carry. She launched her label at a time when everyone thought that the definition of a handbag was strictly European, all decades-old serious status and wealth," Wintour said. "Then along came this thoroughly American young woman who changed everything. There was a moment when you couldn’t walk a block in New York without seeing one of her bags, which were just like her; colorful and unpretentious."

But none have the institutional authority of Wintour, whose word has come to define what "fashion" really is.

"Kate designed with great charm and humor, and built a global empire that reflected exactly who she was and how she lived," Wintour continued in her tribute. "Long before we talked about ‘authenticity’, she defined it."
