Invite yourself. The rules are simple. If you didn't get an invite, you're not invited. It is that simple. This includes giving yourself a plus-one when the invitation didn't specifically state that you're allowed one. Don't ask for an invite, it is rude and puts the bride and groom in an awkward position. If you have to ask, the answer is no.
Don't RSVP. If an invite calls for an RSVP and you do not, then the couple isn't sure whether you'll attend or not, and not attending wastes someone else's opportunity who would have been invited in your place. If someone extends an invite to you, respond and in good time.
Wear something inappropriate. Like white, when you're not the bride, or showing up in your favorite shirt from your college years. Weddings are black tie affairs unless otherwise stated.
Talk smack. Complaining about unnecessary things, asking useless questions and guessing about how much the wedding cost, asking for special treatment and sulking when you don't get your way to any and everyone, comparing with other weddings you've attended, are all examples of talking smack. Don't do it!!
Don't bring a gift. It is wedding etiquette 101 to bring a gift when invited to a wedding. It doesn't have to be elaborate or expensive, gifts are a polite way to wish the couple well. This is one area where the thought really counts.
We all have experiences with worst wedding guests, (some of us are guilty of this), the list is endless, but the objective is to be cordial and respectful of someone else's day.
