Often the finishing touch to a man's clothing, the necktie helps him stand out from the crowd. A good necktie should match your physique and clothing style. Pay attention to the length and width of the necktie - the necktie should be no more than 3 - 3.75 inches (7.5 - 9.5 cm) wide and long enough for your belt buckle.
In addition to your body type, make sure the necktie's width matches the size of the blazer's lapel. For example, if it is a mature dress, you can choose a necktie with a semi-solid color or a light pattern to match a solid-color suit. If you want to stand out, wear a shirt with a necktie in a bold color.
The key to wearing the width of patterned knitted ties is to make sure the pattern doesn't conflict with the pattern on the garment (stripes plus dots, not stripes on stripes).
