We respect the convention of a white or sky blue dress shirt. We might add stripes or plaids, or even try a pink shirt. But we will never ever pair a dark dress shirt with a suit. It makes us fashionable and creative in an urban way that we don’t like.
Perhaps we shouldn’t be that conservative though. Perhaps we should try something different. Perhaps we should try a dark blue dress shirt one day. The dramatically monochromatic effect may have a charm of its own.
