FILE - In this June 9, 1982 file photo, Britain's Prime Minister Margaret Thatcher, right, smiles with satisfaction as President Ronald Reagan makes a farewell speech outside her Downing Street office in London prior to his departure for Bonn. It is not often that the president of the United States needs to seek fashion advice. But when Ronald Reagan was getting ready for a visit to England as a guest of Queen Elizabeth II in June 1982, his people had an important question for the Brits: Just what does one wear to go riding with the queen in the magnificent horse country surrounding Windsor Castle? The answer: Something smart, but casual, of course. Riding boots, breeches and a turtleneck sweater would do fine _ no need for formal riding attire. The fashion inquiry is but one tidbit contained in nearly 500 pages of formerly Confidential documents relating to the Reagan visit being made public Friday, Dec. 28, 2012 by Britain’s National Archives.
