A: Have the party whenever you'd like: as soon as you get back from the honeymoon, or even three to four months afterward. (Wait longer than a year, however, and the guests may not be as excited to come and celebrate.) If you're throwing a formal party, tuck a wedding announcement inside the envelope along with the invitation. The invite wording goes like this: Mr. and Mrs. (your names here) request the pleasure of your company at a reception Sunday, the first of August time, place, etc. If you're having a less formal party, you can get more creative with both your wording ("Join us for a celebration of our recent marriage!") and the invitations. Maybe you can even build the invite around a photo of the spot where you said I do.
