“You should be better dressed than everyone else in the room, but don’t overdo it,” says Brad Sherman, vice president of Hubert White, the downtown Minneapolis men’s clothing store that dresses many a CEO. “If your team is really casual, don’t show up in a 3-piece suit. Come in a level above, but not two or three levels above.” A jacket, Sherman says, is a universal go-to. It need not be extremely tailored and no tie is required, but a jacket “commands something. In the end, that’s what you want.”
