The atoms form positive and negative ions which attract to each other. Ionic compounds are composed of large numbers of positive ions (cations) and negative ions (anions) so that the amount of positive charge equals the negative charge. In covalent bonds the electrons are shared between two bonded atoms.
Conversely, a white or bright shirt should be toned down with a darker tie. Avoid wearing a striped tie with a striped dress shirt unless the pattern of the shirt is very subtle. 2.

If the trousers you are wearing are navy blue, select a tie whose dominant color (the color that occupies the most space in the pattern) is also navy blue. 3.
Of course, as long as the color, print, and texture of your tie, shirt and blazer match. For example you don't want to wear a silk shantung or satin silk bow tie with a felted wool blazer or cord button down shirt. The weight and texture of each and every pieces should compliment each other. Mixing print is tricky.
