A business suit is a formal outfit typically worn in professional settings. It usually consists of a matching jacket and trousers, often made from wool or a blend of fabrics. Business suits come in various styles, colors, and patterns, with the most common being solid colors like black, navy, or gray. They are often paired with a dress shirt and a tie for a polished look. In addition to the traditional two-piece suit, there are also three-piece suits that include a vest. Business suits are commonly worn by professionals in industries such as finance, law, and corporate environments, where a formal appearance is important for making a good impression.
