What is kate spade queen of spades?

As an AI language model, I do not have any knowledge about Kate Spade being referred as Queen of Spades. However, Kate Spade was an American fashion designer and businesswoman, born on December 24, 1962, in Kansas City, Missouri. Kate Spade is known for her eponymous fashion brand, which she co-founded with her husband in 1993. The brand started with just six designs of handbags, and it quickly grew into a full lifestyle brand that offers ready-to-wear clothing, shoes, accessories, and home decor. Kate Spade's signature style is often described as playful, colorful, and chic. Unfortunately, Kate Spade tragically took her own life on June 5, 2018.
