This is a perfect example of an outfit that complements a moderate contrast. The light blue against the brown of the suit is anchored with the darker blue of the tie and pocket square.
You also have the tortoise-shell sunglasses that play off the brown in the suit. Lastly, solid shirt, striped tie, dotted square. Not only does this guy play his color perfectly, he’s wearing three different patterns and they all work well together. This is a solid example of a well-put-together man.
