Abstract: A necktie retainer that restricts movement of the necktie by providing a full flexure tensor member attached to the upper garment of the wearer, a necktie movement governing length of filamentary material with full flexure, distributed direct mechanical attachment to each rear folded portion of the larger end of the necktie. The movement restriction is facilitated through the use of a necktie with a cross member and employing a detachable member on the tensor member that for retention uses the cross member width dimension and for attachment and release uses the cross member thickness dimension. The retainer accommodates different garment and necktie constructions, does not have parts visible from the front and permits relative movement of the central parts of the necktie.
