A bow tie or dicky bow is a type of neckwear, distinguishable from a necktie because it does not drape down the shirt placket, but is tied just underneath a winged collar. A modern bow tie is tied using a common shoelace knot, which is also called the bow knot for that reason. It consists of a ribbon of fabric tied around the collar of a shirt in a symmetrical manner so that the two opposite ends form loops.
