Celebrities react to Kate Spade's death at 55

The fashion world was rocked Tuesday when it was revealed that Kate Spade, the designer behind one of the most influential brands in America, passed away at age 55. She was reportedly found dead in her New York City apartment by suicide.

The sad news leaves the industry and Kate Spade fans in mourning, with many taking to Twitter to share the influence Spade has had on both the trade and their personal styles.

Fashion designer Liz Lange talked about how Spade was "the nicest woman" and acted as her advisor as she took her start in the industry with her maternity brand. Chelsea Clinton, like all of us, recalled her first Kate Spade bag, given to her by her grandmother.

Ivanka Trump also tweeted about her tragic death and linked out a number for those who are struggling with mental health to give a call.

Steven Kolb, the president of The Council of Fashion Designers of America, remembered the impact Spade has had on the industry while others such as Rosie O'Donnell reached out to the designer's brother-in-law, actor David Spade.

Spade began her iconic brand in 1993 with husband Andy Spade. She leaves behind a 13-year-old daughter, Francis.
