Royal Ascot is a unique occasion in the British social season and arguably the last where formal day dress is still required. Ascot is attended by royals, movie stars, the international jet set, the British establishment and also every strata in society, all united in their mission to dress their best for an occasion led by the presence of HM The Queen. "Fashion at Royal Ascot" is a breathtaking sweep through the history of international fashion seen through the prism of this unique occasion. James Sherwood, who is not only the BBCs Royal Ascot fashion commentator but will also be acting as the fashion commentator for the Royal Wedding in April 2011, has written the text, which is arranged chronologically in five chapters interspersed with twelve photo-essays.
