Newlyweds aren't the only ones in debt after their weddings -- a new survey reveals that guests are also feeling the financial strain.
Five percent of all adults and 9 percent of 18- to 34-year-olds (who make up the bulk of wedding guests) said they had gone into debt from attending weddings.
Last month, a study by American Express found that the guests expect to spend an average of $539 for each wedding they attend this year.
And while it is perfectly acceptable to turn down a wedding invitation because you can't afford to go, according to celebrity wedding planner Sharon Sacks, other etiquette experts say that you must send a gift if you were invited, even if you don't attend.
