For the modern man, a tie bar should not extend more than 1/2 to 3/4 of the way across the width of the tie. For a more classic or conservative look, select a tie bar that matches the full width of your tie. No matter your preference, never wear a tie bar that extends beyond the width of your tie or the Gods of Style will manifest pouring red wine on your brand new white dress shirt.
The best tie bar placement allows the tie bar to be seen even with your suit jacket buttoned all the way up.
What color tie bar should I wear?
If you prefer to play it safe, go with gray or silver, with gold a close second. Try to match the metal polish of your tie bar with your jacket buttons, cufflinks, watch or belt buckle. If you feel it compliments your style, don’t be afraid to wear less common metals and go with patterned, colored or novelty tie bars. A wild or funky tie bar can add pop to an otherwise subdued outfit. The color of the tie is worth taking into consideration when choosing a tie bar but there are no hard and fast rules.
