I wrote about the relatively rare window or box pane patterned suit this past April, and thought it useful to show an example of the mid-weight windowpaned worsted at work, as it were, on the fine figure of Dr. André Churchwell. The good doctor's windowpanes (I know of at least two of them) are less conservative than my own, which with only one exception are so discreet as to be relatively unnoticeable. That discretion makes them useful in very conservative settings but the more noticeable versions are perfectly acceptable everywhere else, provided that the wearer does not mind drawing extra attention.
Churchwell's non-directional silk foulard necktie and solid shirt are the right type and amount of pattern for his check. Pink in particular is always a good mate with gray. Another choice could have been a shirt in the color of the check itself, which would serve to blend the elements together and draw an observer's eyes to his face. That would reduce the visual impact of the suit, which can be a useful technique from time to time.
Either way, the windowpane is a sign of a man in style.
