She's the royal belle of the ball!

On Wednesday night Mary and Frederik donned their finest for the gala at the Smithsonian Arts and Industries Building in Washington.
Mary lit up the room in a strapless patterned number, which showed off her incredible figure. The mother-of-four completed her evening look with diamond drop earrings and had her hair twisted into an elegant up-do.
Frederik made her dapper dance partner in a navy tuxedo and bow tie.
