The bow tie has its origins in the 17th century when Croatian mercenaries began wearing them to prevent shirt collars from separating. Over time, bow ties became associated with the upper class and professionals like lawyers and doctors. In the 20th century, bow ties were mainly worn for formal occasions with black and white being the most popular colors. Today, bow ties are regaining popularity beyond formal wear and are seen as a style choice over a status symbol. Modern bow ties come in many colors, sizes, materials and styles to suit different tastes.
