It's hard to find a pop diva that's had more of an influence on fashion than Madonna. She's reinvented herself more times than X-men's Mystique: starting out in the 80s with her thrift shop rebel look (complete with a good hundred rubber bangles and graffiti-covered denim), before revealing the more adventurous outfits in the 90s (see above picture). In more recent years, we've seen her writhing in the tightest of tight leotards in her music videos and sporting top hats with canes on stage, but nothing will compare to the ribbon-haired, fishnet ensembles of the older decades.
