The eye soon stops noticing a steady diet of blue, cream and white shirtings. Offer it alternatives in the form of secondary colors, such as these Thomas Mason shirtings of orange, green and lavender stripes. Try pairing orange with a tan suit, green with gray and lavender with navy. Add a conservative necktie that picks up either the color of the stripe or of the suit itself, and a pocket square that's only loosely related to any of them.
A collection of patterned shirts in colors other than blue gives a man the opportunity to quietly differentiate his dress compared to what's usually seen in the United States. There are exceptions, but retailers in this country tend to offer a wide variety of neckties and a smaller selection of shirts in order to reduce their inventory requirements at the expense of variety in their customers wardrobes.
Choose secondary colors.
