This year marks the centenary of the UK edition of the influential fashion magazine – and the opening of an exhibition celebrating its role in British societyCelebrating your 100th birthday if you’re British means, for one thing, a personal message from the Queen. To commemorate British Vogue magazine’s centenary this year, editor Alexandra Shulman reversed the tradition and published a public paean to the monarch marking her 90th birthday, praising her “unique grandeur” and examining how her “considered wardrobe” had played a central role in her reign, diplomatically, culturally and socially.
