Much fuss was made over Obama's jacket removal on his first day in the Oval Office because he was breaking a rule of the Bush administration: wear a coat and tie at all times. (David Axelrod later explained it was because the president likes to crank up the thermostat.)
But the Bush dress code remained in place on weekends, whereas his successor has implemented an even more informal weekend style.
Over the weekend, Mr. Obama's first in office, his aides did not quite know how to dress. Some showed up in jeans (another no-no under Mr. Bush), some in coats and ties.
So the president issued an informal edict for "business casual" on weekends -- and set his own example. He showed up Saturday for a briefing with his chief economic adviser, Lawrence H. Summers, dressed in slacks and a gray sweater over a white buttoned-down shirt. Veterans of the Bush White House are shocked.
