Couples may bear the brunt of most of the wedding expenses, but they're not the only ones who have to shell out big bucks for their Big Day.
Wedding guests must deal with the costs of transportation, gifts, wedding-appropriate clothing, child-care, pre-wedding celebrations and more -- often several times a year.
As a result, guests are spending less on weddings, according to recent research conducted by Echo Research for American Express. In an online survey of 1,500 consumers, researchers found that guests expect to spend an average of $339 to attend nuptials.
Those who are asked to be in the wedding typically have to shell out more dough than the average guest. However, that cost is going down as well. People involved in wedding parties are expected to spend roughly $377, compared to a whopping $539 in 2011.
