In between the many dramatic scenes and unexpected twists, Hamptons' most-stylish ladies donned their best party getups for Nolan Ross' housewarming on last night's episode of Revenge, but the standout look from the event came from the host himself. "If Nolan is going to throw a theme party, he's going to have the best costume!" the show's costume designer Jill Ohanneson told InStyle.com. "We've actually never seen Nolan throw a party at home with a fun theme, so it was a great one to dress. We spent a lot of time working on the extras to makes sure we had a whole range of people in striped swimsuits, and we wanted the waitstaff to look like an homage to Jean Paul Gaultier's perfume ads -- a bunch of great-looking people in nautical-inspired outfits." Mission accomplished! And despite being called out in front of the crowd by Emily Thorne, Victoria stayed graceful as ever, with an amazing dress to match her unfaltering mood. "It doesn't matter how you go at her, she always has the perfect rebuttal or response. She's unflappable," Ohanneson added. We caught up with Jill to get the details on what all of our favorite characters wore for the third episode of the season.
