Bob Mackie is one of a handful of designers to work with success in the related but disparate fields of theater and fashion design. He is probably best known for the wittily revealing, glamorous beaded and feathered ensembles he designed for actress and singer Cher since the early 1970s. This collaborative image remains so strong that to visualize Cher is to see her dressed by Mackie. His true genius as an interpretative designer, however, can best be seen in his work for comedian Carol Burnett.
