Spoiler alert: This feature contains spoilers on Castle Season 6, Episode 14, aka Dressed to Kill. Stana Katic plays the lovely bride, Detective Kate Beckett. Nathan Fillion plays the dashing groom, mystery writer Rick Castle. No wedding suit for the "ruggedly handsome" NYPD consultant yet?

In Castle Season 6, Episode 14, Rick Castle learns of Kate Beckett's brief modelling stint for "Modern Fashion." Frances Fisher guest stars as Matilda King.

Martha Rodgers (Susan Sullivan) tries to help Beckett in picking a wedding dress, but the future mom-in-law's taste is just way off. Beckett just doesn't like "girly" wedding gowns.

Beckett finds a wedding dress by fate, though. But how she reacts when she sees herself in the mirror has worried some Caskett fans. Is this a sign of wedding jitters? Watch the video below or check out this wedding dress photo from Castle's Facebook page.

Toward the end of the episode, however, Beckett reveals to Castle why their wedding has somehow dampened her spirits. Castle Season 6, Episode 14 has a happy ending, after all. The wedding is still very much on!

Beckett's wedding gown is a work of fantastic Caskett art by Castle costume designer Luke Reichle. The materials that brought the chic design together include "reembroidered French silver bullion lace with a skirt of silk taffeta and organza," TVGuide.com reported.
