Tuesday, November 9Other than Tom Wolfe and the late Oscar Wilde, writers are sartorially deficient. They all dress like grad students who woke up late for that 1 p.m. Freshman Comp section they should never have agreed to teach. But Wil Haygood seems to want to shake that trend. He's not only a staff writer for the Style section of the Washington Post, he also authored a book on the ever-snappily dressed Sammy Davis Jr. (the highly regarded In Black and White: The Life of Sammy Davis Jr.). So you can be sure that Mr. Haygood will look good while he's reading from his works at the Anheuser-Busch Hall on Washington University's campus (Forsyth and Skinker boulevards; 314-935-5576) at 8 p.m. as part of the free "The Smart Set" reading series. In this instance only, perhaps they should change the name to "The Smartly Dressed Set."
