Last week, as the Twitterati and the talking heads tied themselves in knots over the nonstory of Michelle Obama doing like her peers Hillary Rodham Clinton and Chancellor Angela Merkel of Germany and eschewing a head scarf on a visit to Saudi Arabia, an actual political sartorial revolution was, in fact, taking place elsewhere.

I am talking, of course, about the newly elected Greek Prime Minister Alexis Tsipras and his staunch rejection of the tie. As a piece of political stagecraft, it has been exemplary.

Mr. Tsipras did not wear a tie during the campaign. He did not wear one during his formal swearing-in. He did not wear one when he met with the European Parliament president, Martin Schulz (who did: a light blue-dark blue diagonally striped number). And now it looks as if his new cabinet is following him.
