Supercalifragilisticexpialidocious (collection)

Supercalifragilisticexpialidocious, sometimes shortened to Supercalifragilistic, is the twentieth collection by British designer Alexander McQueen, released for the Autumn/Winter 2002 season of his eponymous fashion house. Its title comes from the Mary Poppins song "Supercalifragilisticexpialidocious" (1964). Supercalifragilistic was primarily inspired by the Gothic aesthetic of American director Tim Burton, as well as fairy tales, English school uniforms, and the history of the French Revolution. The collection was heavily sexualised with concepts from fetish fashion such as leather harnesses and sexualised school uniforms. Historicist elements were drawn from the French queen Marie Antoinette, known for her interest in fashion.

The collection's runway show was staged on 9 March 2002 at La Conciergerie, a former prison in Paris where Marie Antoinette had been imprisoned before her execution. Compared to the fairly low-key previous season, Supercalifragilistic marked a return to the macabre theatre McQueen was known for. Tim Burton styled the invitation and the dim, moody lighting. Fifty-seven looks were presented, beginning with a model leading a pair of wolf-dogs down the runway.

Response to the collection was positive, and it is well-remembered in retrospect. Sales were strong, and several designs from the show were seen on the red carpet, particularly a plum-coloured peasant dress. Gwyneth Paltrow was criticised for wearing an ensemble from the collection, a braless see-through top with black skirt, to the 74th Academy Awards. Critical analysis has focused on the collection's Gothic aesthetic and sexuality. Various museums hold items from the collection, some of which have appeared in exhibitions like the retrospective Alexander McQueen: Savage Beauty.
