A tie pin is a small accessory used to secure a necktie to the shirt, preventing it from moving around or getting out of place. Typically made of metal, tie pins come in various designs and styles, allowing individuals to express their personal taste while maintaining a polished appearance. To use a tie pin, it is usually inserted through the tie and the underlying shirt fabric, ensuring it holds both in place. This accessory is often worn for formal occasions, such as business meetings or weddings, and can complement other accessories like cufflinks or tie clips.
