I have over 200 shirts. Ascot Chang's marketing has said that a good shirt should last through 50 washings. As I don't buy cheap shirts, I've got a twenty-five year supply, easily.But do you wear them as often?
The black shoe analogy may be relevant for some. While some individuals may own far more shirts or shoes in other colors, they tend to wear white shirts and black shoes far more frequently, particularly in a business setting.
But every two years I order three white Brooks Brothers shirts to replace the last set that are worn out.
