On our list of one-name entertainers with show-stopping style, Cher certainly holds her own. From the midriff-baring costumes she sported on "The Sonny & Cher Comedy Hour" to the larger-than-life Bob Mackie headpieces she's donned as a solo act, Cher isn't afraid of taking risks.

The "Goddess of Pop's" unapologetic style has been remixed by pop princesses like Katy Perry, Rihanna and Lady Gaga. While we may gasp at these modern fashion statements, Cher's philosophy on image puts it all into perspective: "Until you're ready to look foolish, you'll never have the possibility of being great."

So in celebration of Cher's 67th birthday on Monday (May 20), we are taking a look back at her unforgettable fashion moments. Vote for your favorite in the slideshow below.
