Abstract: A necktie restraining shirt is designed to selectively restrain or conceal the rear tail portion of a necktie. In a first embodiment, the shirt is provided with a small opening into which the rear tail portion of a necktie can be inserted. In a second embodiment, the shirt is provided with a loop of material through which the rear tail portion of the necktie can be positioned with the front portion of the necktie then overlying the tail portion so as to conceal it. In a third embodiment, the shirt is provided with both an opening to receive the rear tail portion of the necktie and a loop of material for receiving the front visible portion of the necktie. In this latter embodiment, the tail portion is concealed inside the shirt while the loop of material functions in the manner of a tie pin so as to prevent the front portion of the necktie from flopping around.
