Hopefully the arrival of President Barack Obama will offer a chance to revisit the sartorial standards of international summitry. Part of George Bush's being-in-charge look was the crisp suit and flag pin. Here Brazilian President Lula shows one can keep the flag pin and dump the tie even when others around are wearing their's. Since it's never been clear how wearing a tie makes a meeting more productive, perhaps Lula is on to something. But is that look now too Persian?
