A necktie is a long piece of cloth worn around the neck, typically under a shirt collar. It is often made from materials like silk, polyester, or cotton and comes in various colors and patterns. Neckties are commonly associated with formal or business attire, adding a touch of style to an outfit. Neckties can be tied in different styles, with the Four-in-Hand and Windsor knots being among the most popular. They are often worn during special occasions, such as weddings or job interviews, and can reflect personal taste or professional standards in fashion.
