In June 1953, a 27-year-old Princess ascended to the throne in a coronation gown bejeweled with symbolism. It was a dress that could only have been worn by a Queen of England: embroidered with the floral emblems of the United Kingdom and the Commonwealth and - at the request of Elizabeth herself - made of satin, like her wedding dress six years earlier.
Granted, the Queen has never been as fashion-forward as her sister Margaret - but that doesn't mean her style isn't unique. Much like her first coronation gown, Queen Elizabeth's colourful wardrobe has never failed to assert her royal image - and it's evolution over the decades has made her a fashion icon with both style and purpose.
At the start of her reign she favoured fairytale ball-gowns and shimmering satin frocks. In the 60s her style moved towards much more distinctive tailored, full-skirted suits, which accentuated her tiny waist. Over the years, these tailored suits have become her staple, emphaising her status as a world leader.
Queen Liz is the epitome of chic, famous for wearing bright, block colours, pearl necklaces, pristine white gloves and plaid skirts, accessorising her look with a few pieces of elegant diamonds.
She has not put a sartorial foot wrong and has never had a fashion faux pas. Her impeccable style is what has ensured her place as an icon with many looking to her as style inspirtation, and even Dolce & Gabbana basing an entire collection around her signature looks.
