Bob Mackie was first tasked with dressing Cher in 1967 when she appeared as a guest on “The Carol Burnett Show.” “We hit it off right off the bat,” Mackie tells Variety, and the rest is history.

At the time, Cher called on Mackie to dress her for special occasions, and when “The Sonny and Cher Show” aired, she turned to him to create her costumes. The show was meant to be a replacement series only for the summer, but turned into a huge hit.

Mackie has been designing for Cher ever since. From her show-stopping red carpet events to her dazzling outfits on tour, Mackie says he has created hundreds of outfits. Most recently, he has designed looks for the singer’s Las Vegas residency and Dressed to Kill tour. “It’s hard because I don’t have pictures of everything and I don’t know where they all are,” Mackie says with a smile. “She had anywhere from 15 to 30 outfits in one show, so after a while, you forget you even did it.”

In honor of Cher’s 75th birthday, Mackie has hand-picked his favorite ten outfits from over the years — plus a bonus look he hopes she will wear one day.
