A blue suit has, for too long, conjured up a picture of a 'Sunday-go-to-meeting' suit in blue erge, either too dark (that is to say, too much like the true navy blue which is almost black) or in what one calls a bad navy, which is one that is too purple. In point of fact a good navy is a very becoming color to almost everyone, male or female. It is not actually navy blue at all, but what we would call a French navy, a light navy with green cast and never a red. It is very clean looking with a white shirt, and very elegant looking and harmonious with a blue shirt. It is an ideal color by articifial light and will go a deep black, wheras black itself may go brown or greeny. A blue suit is, therefore, an excellent late-day garment when a dinner jacket is not required.
