When: July 5, 2009
Where: Walking to Air Force One before leaving Andrews Air Force Base in Maryland for a trip to Moscow, Russia
Wearing: Cardigan, printed dress, belt, and double stranded pearls
Why it mattered: In 20 years, when people start dressing up as legendary First Lady Michelle Obama for Halloween—as they inevitably will do—the costume formula will be simple, says Dincuff: "Cardigan, printed dress, belt, and costume jewelry, especially a necklace." Here, in July 2009, is an early example of what would become her signature daytime look.
