McQueen, the controversial creative genius who clothed the world's biggest stars, committed suicide on the eve of his beloved mother's funeral, seven months ago.
Many of the mourners chose to wear McQueen's creations. Campbell wore a flamboyant feather creation and gold-heeled platform boots while Parker opted for a black trench and opulently frilled white dress.
But Moss cut a sombre figure in a leather pencil skirt and tuxedo jacket.
US Vogue editor Anna Wintour and British designers Pam Hogg and Stella Mcartney were also present amid the sea of black designs.
The 40-year-old's body was discovered by his housekeeper in a wardrobe at his flat in Mayfair, central London, the day before his mother Joyce's funeral.
An inquest heard the designer hanged himself after taking a cocktail of cocaine, sleeping pills and tranquillisers.
