How do you take your suit look down a notch while still looking business appropriate? It needs to be the right suit with the right shirt. Choose a shirt with more pattern and add a pocket square to complete the look. Changing out one blue poplin shirt for another blue poplin shirt won’t cut it. Mix in a floral, a Bengal stripe, a plaid—and while you’re at it, changing the texture will help you keep things interesting—a cotton slub on Tuesday to a piqué on Wednesday will alter the character of your suit.
