Once upon a time the white blazer. Hanfry Bogart, Cary Grant, Vittorio De Sica were used to wear it in lots of their movies. They were Gentlemen before to become iconic actors . I wear this one, sartorial, since ten years, once or twice in the summer, when I’m tan. It looks very good. With a white shirt and light blue trousers. Never forgetting a well matched pocket square, because as you know class is in the details.
