Color Is Hard: Patterns Are Not Too Simple Either

Sometimes, a bit of daring (and the passive voice) is called for.  Continuing with my herringbone fixation, here is a navy herringbone suit with dark blue herringbone socks, the pattern perhaps twice the size of the pants'.  Just enough visual contrast to keep from looking matchy.  (If your patterns are too close to each other conceptually, in size, shape, direction, color, etc, it just looks funny, as if the Mona Lisa had a small third eye on her neck.)
