Socks are the part of a man’s wardrobe that generally goes overlooked. Most men simply follow the general rules of road and stay quite conservative (those rules being: white socks for athletic attire and sneakers, dark socks for dress attire or leather shoes and the socks should be the same color as the pants in a darker shade).
When it comes to what you wear with your leather dress shoes you have the opportunity to break from humdrum of plain dark socks and show some personality. For the less adventurous, in more casual situations, this can be done with a simple argyle in rather subdued colors. Generally the brighter the color of the sock and the more it clashes the more adventurous the individual must be.
For more formal situations solid colors are more acceptable. If you are wearing a dark navy or black suit with black shoes colored socks can break up the two. Or they can be used simply to add personality to your ensemble.
Whether you choose a patterned sock, such as an argyle, or a solid, coordinate a color in the sock with a color above the waist.
Your socks are something that are not normally seen unless sitting making them a great way to start being more adventurous and showing your sense of style.
