Fantasia, by its strictest definition, is a musical term: describing free improvisation and contrast of musical treatments that seldom follow textbook rules. Appropriate then that the same word should be the title of Nick Knight's latest fashion film: a free-wheeling exploration of joyous, unbridled movement in model and clothing alike. Harness to this the riotous creativity of some of fashion's greatest names and you have a mesmerising, full-throttle trip around the most sensational sartorial propositions of the past ten years. Worked to their fullest extent by the dynamic duo of Lily Donaldson and Jourdan Dunn, the array of outfits on show are a fashion fantasy - in the very truest sense of the term.
