In yesterday's Guardian, Madonna-hater Germaine Greer presented us with the concept of "the power pearl" as sported by Condoleezza Rice and, lately, Michelle Obama. "Power pearls are pure white and large, anything from 11mm in diameter to 16mm, in a single strand, which must hang within rather than over the neckline. The size reveals that power pearls are not properly "natural". The power pearl, says Greer, manages to symbolize class, confidence and even a touch of reassuring dowdiness, traditionally feminine without a hint of jarring sexuality. "Power pearls are glamour, bravado and insolence." Or...sometimes a pearl is just a pearl? [The Guardian]
