Suit trousers are a type of formal pants designed to be worn with a matching jacket as part of a suit. They are typically made from materials like wool, cotton, or polyester, providing a polished appearance suitable for business or formal occasions. Suit trousers often feature a tailored fit, with a straight or slightly tapered leg, and may include details like pleats or pockets. These trousers come in various colors and patterns, with navy, black, and gray being the most common choices. They are usually worn with a dress shirt and tie, completing a sophisticated look for events such as weddings, interviews, or office settings.
