Invitations to a dinner are usually issued several days before the appointed time—the length of time being proportioned to the grandeur of the occasion. On receiving one, you should answer at once, addressing the lady of the house. You should either accept or decline unconditionally, as they will wish to know whom to expect, and make their preparations accordingly.
2. Dress.
You must go to a dinner party in "full dress." Just what this is, is a question of time and place. Strictly interpreted, it allows gentlemen but little choice. A black dress coat and trowsers, a black or white vest and cravat, white gloves, and pumps and silk stockings were formerly rigorously insisted upon. But the freedom-loving "spirit of the age" has already made its influence felt even in the realms of fashion, and a little more latitude is now allowed in most circles. The "American Gentleman's Guide" enumerates the essentials of a gentleman's dress for occasions of ceremony in general, as follows:
"A stylish, well-fitting cloth coat, of some dark color and of unexceptionable quality, nether garments to correspond, or in warm weather, or under other suitable circumstances, white pants of a fashionable material and make, the finest and purest linen, embroidered in white, if at all; a cravat and vest of some dark or neutral tint, according to the physiognomical peculiarities of the wearer and the prevailing mode; an entirely fresh-looking, fashionable black hat, and carefully-fitted modish boots, white gloves, and a soft, thin, white handkerchief."
A lady's "full dress" is not easily defined, and fashion allows her greater scope for the exercise of her taste in the selection of materials, the choice of colors, and the style of making. Still, she must "be in the fashion."
3. Punctuality.
Never allow yourself to be a minute behind the time. The dinner can not be served till all the guests have arrived. If it is spoiled through your tardiness, you are responsible not only to your inviter, but to his outraged guests. Better be too late for the steamer or the railway train than for a dinner!
4. Going to the Table.
When dinner is announced, the host rises and requests all to walk to the dining-room, to which he leads the way, having given his arm to the lady who, from age or any other consideration, is entitled to precedence. Each gentleman offers his arm to a lady, and all follow in order. If you are not the principal guest, you must be careful not to offer your arm to the handsomest or most distinguished lady.
