NEW YORK — Bob Mackie, the costume designer who defined mid-century American glamour, has died at 87. His studio confirmed the death this week, prompting tributes from Cher, the Council of Fashion Designers of America and Hollywood peers.

Mackie dressed Cher, Marilyn Monroe, Diana Ross and Carol Burnett across a six-decade career, earning nine Emmy Awards and multiple Academy Award nominations for costume design. He was best known for the beaded, sheer 'naked' gowns that made red-carpet history.

Cher, who wore Mackie designs throughout her career and at the 1974 Met Gala, was among the first to publicly mourn him. "Bob made women feel like the most glamorous version of themselves," she said in a tribute, calling him "a genius and a true friend."

The Costume Designers Guild and CFDA praised his influence on both stage and screen. Museums and archives, including the Metropolitan Museum of Art's Costume Institute, hold examples of Mackie's work, and curators signalled renewed interest in his legacy.

His death coincided with New York Fashion Week, prompting designers to reflect on his impact on American showmanship.
