What becomes a legend most? How are those cultural superstars chosen, the ones whose very names invoke awe, wonder, or at least a gasp? Alexander McQueen: Savage Beauty, the comprehensive retrospective of the late designer’s ravishing raiment now on view at the Metropolitan Museum of Art certainly provides a clue. With an hour and a half wait to enter (on a good day), a de facto gala in his honor and almost unanimous praise from critics, the McQueen legend continues to thrive in the eerie, operatic halls of the exhibition space. He may have a spectacular artistic output, and he may have defined an era of rising fashion stars, but the question remains how his deification came to be, how he came to define 21st century fashion with a short, tragically romantic career.
