A spread collar is a type of shirt collar characterized by its wide distance between the collar points. This design allows for more space around the neck, making it suitable for wearing with a variety of tie knots, including larger ones like the Windsor knot. Spread collars are often found on dress shirts and can enhance the overall appearance of formal attire. Typically, spread collars come in different styles, such as the classic spread and the extreme spread. They are popular in both men's and women's fashion, providing a modern and sophisticated look. The versatility of spread collars makes them a favored choice for both business and casual settings.
