Today we celebrate the birth of the one the most gifted entertainers in the world: Cher. Over the last four decades — yes, decades — the superstar has starred in award-winning films, produced a plethora of uplifting I-am-woman-hear-me-roar ballads, and forged ahead of the style front to truly be one of a kind. Though the crooner's onstage presence is just as dazzling as her high-octane performance looks , it's her trendsetting off-duty style that has really captured our attention. From boyfriend blazers and leather miniskirts to sporty-chic separates and mom jeans (you know they're back, right?), it seems Cher is always a sartorial step ahead.
Do we sense a little hesitation? If this list of former Hollywood flames  is any indication, it seems Cher knows a thing or two about turning a man repeller into a man getter. Oh, now you're on board? Great! Let's turn back time to celebrate Cher's most notable off-duty looks — and see which celebrities nowadays are taking a page straight from the fashion icon's playbook.
