As George Bernard Shaw once observed, England and America are two countries divided by a common language. The same might be said of gentlemen's dress in the two countries. Or, rather, three countries as the United States lies somewere between England and Italy in style and though the three have common clothing roots seems to drift further towards the Italians every year.
The English of course are responsible for the basic architecture of jacket, trousers and necktie and have given us most of the great tailors. Further, English conservatism has kept at least some men true to what were the Rules of the City of London. That is to say, charcoal and navy suits, conservative neckties, a bit of flair in the shirts, and black shoes. Always black shoes.
Two trends led the Italians to predominance in North America. The first was that there was never much of a ready to wear market tailored clothing in England, where large chains specialized instead in made to measure clothing before and after the Second World War. I am not aware of any English brand establishing itself in the American market, however the Italians made a significant investment beginning in the 1980s and did get a foothold.
In addition, it rarely gets truly hot in England and that nation's tailors took a while to grow comfortable with lightweight cloth. That period of discomfort meant further opportunity for the Italians, including designer Massimo Bizzocchi in the photo, who worked successfully to get lightweight clothing accepted in the U.S. With that success came the Italian clothing sense as illustrated by Mr. Bizzochi's brown suit and brown striped shirt. That is a combination one would rarely see in England and then usually on men who prove to be visitors from Milan and points south.
In the United States though, Italian style predominates today, having overwhelmed the Brooks Brothers sack suit as well as the Savile Row silhouette and color palette. Visit any department store, and other than the odd U.S. maker the suits on sale are Italian. And the North American men I know who dress in bespoke clothing, clothing that is overwhelmingly English in make as few of the continental tailors visit the United States, wear it in a way that has more in common with the Italians than English.
Two countries separated by a common dress.
