Hair Raiser (1986)
Perhaps Oscar's first great screw-you fashion moment. Snubbed for her performance in Mask, Cher stuns the fastidious Academy by wearing a belly-baring Bob Mackie number that is one part spider, two parts Vegas showgirl. ''I did receive my Academy booklet on how to dress like a serious actress,'' she cracks. Two years later, Cher is named Best Actress for Moonstruck.
