Frances Fisher and Stana Katic

When bride-to-be Kate Beckett (Stana Katic) revisits her past as a model on the Jan. 27 episode of ABC's Castle, she crosses paths with Modern Fashion magazine editor Matilda King (Frances Fisher) and tries on a couture wedding gown plucked from a runway show. The dress, the work of Castle costume designer Luke Reichle, was constructed from reembroidered French silver bullion lace with a skirt of silk taffeta and organza. (Want to copy Kate's look? Expect to spend north of $30,000, says Reichle.)

While Beckett and Castle (Nathan Fillion) have yet to set a date for their nuptials, Katic has an idea of how it should go down. "There's got to be some espionage stunt that screws up the wedding and leads them to city hall to just get it over with," she says. "They are constantly living on the edge, and their wedding day should be no different."
