Another angle is cost. Suits are expensive, because to fit well they need to be tailored. Ordinary people wear them less today than fifty years ago, and this is one of the main reasons. They are semi-formal clothing, good for wearing to the office, but not so good for watching a football match. A trend towards informal dress started in the 1960s and 1970s, and has changed the way many people dress. All the same, high-status men do still wear suits. They "say" something about the wearer, or so it is thought.
