Black calfskin low shoes. Plain black silk socks. Gray striped trousers (the darkest you have). Morning coat and single-breasted black waistcoat. White dress shirt (see that cuffs show three-quarters of an inch below coat sleeves). Stand-up wing collar. Tie and gloves are enclosed. Boutonnière will be at the church. Be at the church yourself at three o'clock, sharp." =THE HEAD USHER= Usually there is no "head usher," but in certain localities courtesy designates the usher who is selected to take the bride's mother up the aisle as the "head," or "first" usher. Very occasionally, too, a nervous groom appoints an especially "reliable" friend head usher so as to be sure that all details will be carried out--including the prompt and proper appearance at the church of the other ushers. Usually, the ushers divide the arrangements among themselves. The groom decides who goes on which aisle. One of them volunteers or is asked to look out for the bride's coming and to notify the groom, another is especially detailed to take the two mothers up the aisle. But very often this arrangement is arbitrarily decided by height. If one mother is very tall and the other very short, they generally go up with different ushers, the tallest being chosen for the taller lady, and one of medium height for the shorter. =THE BRIDESMAIDS' LUNCHEON= In many sections of America, especially in the country and in small towns, brides make an especial feature of asking their bridesmaids to a farewell luncheon. The table is elaborately decorated (invariably in pink with bridesmaids' roses), there is a bride's cake (lady cake) and there are favors in the cake, and mottoes, and altogether it is a "lovely party." In New York there is nothing like that at all. If the bride chooses to give a luncheon to her bridesmaids on whatever day suits her best, there is no objection to her doing so, or in fact, to her inviting whom she pleases to whatever sort of a party her mother is willing she should give. It is not a question of approved etiquette but of her own inclination seconded by the consent of her mother! If her mother "keeps open house," probably they lunch with her many times before the wedding; if, on the other hand, it is not the habit of the family to have "people running in for meals," it is not necessary that she ask them to lunch at all. But whether they lunch often or never, the chances are that they are in and out of her house every day, looking at new presents as they come, perhaps helping her to write the descriptions in the gift book, and in arranging them in the room where they are to be displayed.
