When two well-to-do last names (a Hilton and a Rothschild, for example) join forces in matrimony, the celebration must be extravagant, exotic, and anything but humble.

And though an inherited spot on the international social scene certainly helps, anyone (with enough dough and famous friends) can get married like a socialite.
