Revenge is pretty fun to watch, right? Not only for the amazing storyline—even if totally unrealistic—but also for the fashion. Famed costume designer Jill Ohanneson is the mastermind behind the looks Emily Thorne (Emily VanCamp), Ashley Davenport (Ashley Madekwe), Charlotte Grayson (Christa B. Allen), Victoria Grayson (Madeleine Stowe), and the rest of the cast wear in the show, and we must admit, we like her choices. Tonight’s episode centers on Emily and Daniel’s much anticipated Fire & Ice-themed engagement party, and style-wise revisits the same red outfits we first saw in the pilot. And those red dresses are all designer: Ashley in Alexander McQueen, Victoria in Reem Acra (right), and Charlotte and Emily (left) in Vera Wang. Watch the new episode at 10/9c on ABC tonight to see them all in action, and see more outfits from the show in the gallery.
