A preformed necktie has an insert with a pair of connected diverging closed conduits interconnected by a support. A slide post extends from the support proximate the lower ends of the conduits. A tie portion is wrapped about the insert to form a knot and to become the front tie panel. The two ends of a neck-embracing loop have corresponding zipper panels and pass through the conduits to be joined by the slide and form a rear panel of the tie. The neck embracing loop is tightened or loosened by movement through the knot and slide.
