The arrival in London of the biggest Dior retrospective Britain has ever seen comes with an extra layer of symbolic specialness. From the thousands of paper roses blooming in the garden-themed room to Princess Margaret's 21st birthday gown, the 'Christian Dior: Designer of Dreams' exhibition puts a distinctly British spin on its exploration of the House's revolutionary history. A guaranteed blockbuster, it opens today at the V&A - so don't forget to book your ticket! #DiorDesignerofDreams ? @AdrienDirand
