Queen Elizabeth II has long been the source of public fascination. From the rules she allowed Michelle Obama to break to what she does when greeting important people, the monarch has always intrigued the public. Now, those that are interested in Her Majesty will have an additional place to learn about the member of the British royal family when the book "The Other Side of the Coin: The Queen, the Dresser and the Wardrobe" makes its debut.

According to the Sun, the new project, which will be written by one of Queen Elizabeth's closest advisers, Angela Kelly, is set to give an intimate look at what has gone into dressing the monarch for 25 years. Kelly, who holds the positions of Curator, Personal Adviser, and In-House Designer, was reportedly given "extraordinary permission" to publish the fashion secrets.

This publishing of her "working relationship" with the Queen is said to be the first time that the royal has allowed any member of her staff to publicly speak about what goes on behind closed doors.

As it is set to include previously-unseen photographs from Kelly's personal collection, insight as to how the duo goes about preparing the Queen's outfits for formal occasions, and anecdotes about their friendship, the book will surely be an interesting read for those who remain captivated by the royal.

This would certainly not be the first time that the Her Majesty's royal fashion has been studied. In the past, fans of the royals have also shown an interest in why she always wears bright colors.
