Fashion critic Cathy Horyn paid tribute to the 49-year-old and remembered how her friend began her company on a "shoestring" budget.
"She had an incredible work ethic; if there was one thing that bound all her friends, wherever they were born, it was that," Horyn pens. "And there was no job she wasn't willing to do herself, which became a problem as her company got bigger."
Her hard work and drive paid off because over the years, Mick Jagger's longtime girlfriend attracted a long list of celebrity fans including Sarah Jessica Parker, Angelina Jolie, Michelle Obama,Nicole Kidman, Amy Adams and many more.
But Horyn explains that Scott, like many small designers, still struggled to "manage her business: cash flow, finding the right managers, getting her goods out of Italian factories on schedule."
"Two years ago, our friendship was tested when, after hearing her troubles, I told her she should give herself a time limit to resolve matters or get out. Putting her health in jeopardy because of stress was not worth it, I told her."
Horyn writes that she learned Scott was planning to make the difficult business announcement on Wednesday.
"Still, as painful as the decision must have been for her, I wouldn't draw any conclusions from it about her state of mind," Horyn concludes. "Nor should any credence be given to reports of a breakup with Mick. It's rubbish."
Scott was found dead of an apparent suicide in her NYC apartment Monday. The 70-year-old Rolling Stones rocker made a touching and mournful statement on his Facebook page on Tuesday.
"I am still struggling to understand how my lover and best friend could end her life in this tragic way," Jagger posted with a beautiful photo of his late partner. "We spent many wonderful years together and had made a great life for ourselves."
