A new episode of Dallas premiered last night, and we caught up with the show's costume designer, Rachel Sage Kunin, to get the exclusive details about the Texan looks she created, including the structured white jacket Rebecca (Julie Gonzalo) wore when she showed up at Elena's (Jordana Brewster) cottage. "I put her in white to show some vulnerability," Kunin said. "I love that this jacket also alludes to having the upper hand given its military style-she's keeping in mind that what she wears has a psychological effect on those around her."
