Wearing a tie is a good way to introduce a personality to an otherwise static look. The standard tie length is a little less than 60 inches and the width at the widest point should be around 5 inches.
The rule of thumb is that the tip of your tie should reach your belt buckle, so the length actually depends on how you wear your slacks or trousers and at no time should they hang lower than your buckle.
To complement the jacket, ties should never clash with its color. If the color of the jacket is loud, the tie should work to tone it down and vice-versa. So, plain ties will work well with striped jackets and colorful ties with solid-colored jackets.
There is a wide variety of styles and colors of neck ties to suit any occasion and you should keep a number of styles and colors in your wardrobe. Never wear printed ties at formal settings; these occasions are only reserved for single-colored ties.
Ties with cartoon prints should never be worn in the office during work hours, but they are ideal for office banquets or other social gatherings. Tie colors are usually your personal choice, but for aesthetic purposes, the color of your tie should be darker than your shirt and lighter than your jacket. The best types to keep are the ones with a solid color because they never go out of style and can be worn with most types of jackets and in any occasion.
