Such an invitation is acknowledged in kind--by an informal note.

It may be of interest to read a letter or two from distinguished persons along these lines. Here, for example, is the delightfully informal way in which Thomas Bailey Aldrich invited his friend William H. Rideing to dinner on one occasion:[1]

April 6, 1882.

Dear Rideing:

Will you come and take an informal bite with me to-morrow (Friday) at 6 P. M. at my hamlet, No. 131 Charles Street?

Mrs. Aldrich and the twins are away from home, and the thing is to be _sans ceremonie_. Costume prescribed: Sack coat, paper collar, and celluloid sleeve b.u.t.tons. We shall be quite alone, unless Henry James should drop in, as he promises to do if he gets out of an earlier engagement.

Suppose you drop in at my office to-morrow afternoon about 5 o'clock and I act as pilot to Charles Street.

Yours very truly, T. B. Aldrich.

And one from James Russell Lowell to Henry W. Longfellow:[2]

Elmwood, May 3, 1876.

Dear Longfellow:

Will you dine with me on Sat.u.r.day at six? I have a Baltimore friend coming, and depend on you.

I had such a pleasure yesterday that I should like to share it with you to whom I owed it. J. R. Osgood & Co. sent me a copy of your Household Edition to show me what it was, as they propose one of me. I had been reading over with dismay my own poems to weed out the misprints, and was awfully disheartened to find how bad they (the poems) were. Then I took your book to see what the type was, and before I knew it I had been reading two hours and more. I never wondered at your popularity, nor thought it wicked in you; but if I _had_ wondered, I should no longer, for you sang me out of all my worries. To be sure they came back when I opened my own book again--but that was no fault of yours.

If not Sat.u.r.day, will you say Sunday? My friend is a Mrs.

----, and a very nice person indeed.

Yours always, J. R. L.

George Meredith ("Robin") accepting an informal dinner invitation from his friend, William Hardman ("Tuck"):[3]

Jan'y 28, 1863.

Dear "at any price" Tuck:

I come. Dinner you give me at half-past five, I presume. A note to Foakesden, if earlier. Let us have 5 ms. for a pipe, before we go. You know we are always better tempered when this is the case. I come in full dress. And do the honour to the Duke's motto. I saw my little man off on Monday, after expedition over Bank and Tower. Thence to Pym's, Poultry: oysters consumed by dozings. Thence to Purcell's: great devastation of pastry. Thence to Sh.o.r.editch, where Sons calmly said: "Never mind, Papa; it is no use minding it. I shall soon be back to you," and so administered comfort to his forlorn Dad.--My salute to the Conquered One, and I am your loving, hard-druv, much be-bullied

Robin.

_To a theatre_

347 Madison Avenue, December 8, 1919.

My dear Miss Evans,

Mr. Smith and I are planning a small party of friends to see "The Mikado" on Thursday evening, December the eighteenth, and we hope that you will be among our guests.

We have arranged to meet in the lobby of the Garrick Theatre at quarter after eight o'clock. I do hope you have no other engagement.

Very cordially yours, Gertrude Ellison Smith.

_Accepting_

My dear Mrs. Smith,

I shall be delighted to come to your theatre party on Thursday evening, December the eighteenth. I shall be in the lobby of the Garrick Theatre at a quarter past eight o'clock.

It is so kind of you to ask me.

Sincerely yours, Ruth Evans.

December 12,1919.

_Regretting_

My dear Mrs. Smith,

With great regret I must write that I shall be unable to join your theatre party on Thursday evening, December the eighteenth. My two cousins are visiting me and we had planned to go to the Hippodrome.

I much appreciate your thinking of me.

Very sincerely yours, Ruth Evans.

For an informal affair, if at all in doubt as to what kind of invitation to issue, it is safe to write a brief note in the first person.

Two or more sisters may receive one invitation addressed "The Misses Evans." But two bachelor brothers must receive separate invitations. A whole family should never be included in one invitation. It is decidedly not proper to address one envelope to "Mr. and Mrs. Elliott and family."

_To an informal dance_

Invitations to smaller and more informal dances may be short notes. Or a visiting card is sometimes sent with a notation written in ink below the hostess's name and toward the left, as shown below:
