In the summer of 1900 the shirt-waist, which was worn almost universally by women, was emulated by men, many of whom assumed, during business hours, unstarched colored shirts worn without vests, while a waist belt replaced the usual braces. •Often the coat was discarded. The comfort of this attire during the heated term was so great that the " shirt-waist man" promises to become a recognized summer institution.
As for evening dress, a considerable latitude of opinion concerning this prevails. During the warm season from June to October—comfort demands much laxity in this respect. As evening dress is never seen in city streets without an overcoat, and as few care to swelter at the dictum of fashion, many men of sense content themselves with a neat ordinary dress. There is a variety of usage in this respect also at the theatre, and it is coming to be imperative to wear evening attire only at formal dinners or at certain fashionable assemblages which make it a requisite. In general, except during the summer, it is a safe rule for the denizen of fashionable circles to change his dress every evening, so as to be prepared for dinner or any other formal occasion. But as the denizens of fashionable circles compose a limited section of the community, an island in the sea of the multitude who claim no such exclusive honor, evening dress, as a general rule, is kept for special occasions, and men at home consider comfort and convenience far more than fashion.
