Abstract: The Hook Button Simulated Knot Adjustable Length Necktie is designed with a top and bottom portion. The top portion is comprised of an upside down half frustum rubber device, with a continuous extension at the top on either side. The top portion also comprises a horizontal adjusting bar. The top portion is covered in fabric to make a simulated tie knot which when worn has the appearance of a conventional tie knot finish. Unique to this invention is the Hook Button installed at the back of the top portion which is used for the necktie to be worn on the collar button. The bottom portion, the tail length, connects to the top portion to complete the finished necktie. The finished necktie requires no assembling by the wearer, it fits securely over the collar button and comfortably remains in place and the bottom portion, the tail length, is adjustable.
