I watched The Queen last night (finally) and one of the fashion notes that stood out was the Queen's pearls. She seems to sport them as daily wear - one strand in the country, three for city and TV speech.
Her pearls are such a part of her appearance that I would bet she is uncomfortable without them. If I remember my historic lore, Elizabeth I made pearls her personal trademark - maybe it's Elizabeth II continuing the tradition? Was this just a movie thing or does she wear often in reality?

My only jewelry that I miss when I don't wear it are my wedding rings and a watch. I do love my pearls (I know Angie is devoted to hers and sports them so much more stylishly than the Queen) but it's been a long time since i wore them .
