What is the proper length for a tie to hang?
Your tie should cover all your shirt buttons and just hang over the waistband of your trousers by about an inch. When tied perfectly, both ends of the tie should be of the same length. To get the ends to come out evenly use a standard four-in-hand knot and start with the wide end of the tie hanging one foot lower than the narrow end. Don`t tie a double Windsor knot if you are over six foot or have a larger than 16 1/2 inch neck as your tie will end up barely at your waist. And only use a quality, full-length tie.
