Queen Elizabeth II surpassed her great, great grandmother Queen Victoria as the
longest reigning monarch last year, and on 21 April she celebrates her 90th birthday.
Monarchs such as Victoria and Elizabeth I are remembered as icons of a period of change. Their fashions were synonymous with the era of their reign. As a new and young monarch in post-war Britain, Queen Elizabeth II became the ruler of a country undergoing political, social and sartorial change.
Never before had fashion been so free and whilst of course no one expected her Royal Highness to step out in a pair of flares and Mary Quant mini, Elizabeth II has remained a stylish and sophisticated icon of British fashion throughout her life. She worked with fashion pioneers such as Norman Hartwell and Hardy Amies, as well as inspiring the likes of Dolce and Gabanna to base their autumn/winter 2008 collection around her.
Captured around the world and through the lens of everyone from Cecil Beaton to Annie Leibovitz, Elizabeth's style is individual to her and endlessly classic. Despite her utter dedication to professionalism and her role as monarch, the Queen has always managed to have a little fun with a wardrobe that has also managed to stay way clear of any form of seasonal disasters.
From the military feminist overalls of her Auxillary Territorial Service uniform in 1945 to her rather daring safari pant suit there are but a few occasions that she has strayed from her trusty fashion formula. Bold colours and perfect day coats worn with simple black patent slip-ons by Anello & Davide of Kensington as well as playful, albeit priceless, accessories and a luxurious classic Launer handbag are the staple ingredients of the Royal wardrobe.
Not many people can claim their their style has remained relevant for nine decades.
As the Queen prepares to celebrate her ninetieth year in style, IBTimes UK looks back on her most fabulous fashion moments.
