Former Secretary of State Madeleine Albright has written a book about her jewelry, of all things. Here's part of the book blurb:
It would never have happened if not for Saddam Hussein. When U.S. ambassador to the United Nations Madeleine Albright criticized the dictator, his poet in residence responded by calling her "an unparalleled serpent." Shortly thereafter, while preparing to meet with Iraqi officials, Albright pondered: What to wear? She decided to make a diplomatic statement by choosing a snake pin. ... From that day forward, pins became part of Albright's diplomatic signature. International leaders were pleased to see her with a shimmering sun on her jacket or a cheerful ladybug; less so with a crab or a menacing wasp. Albright used pins to emphasize the importance of a negotiation, signify high hopes, protest the absence of progress, and show pride in representing America, among other purposes.
Sounds really interesting!
