Born Cherilyn Sarkisian on May 20, 1946, the original diva with a heart was never afraid to push boundaries throughout her six-decade-long career.

The common thread? Outlandish excess and a nod to glam rock. As the pop legend turns 74 today, we celebrate some of her iconic fashion moments to date.
