Last night's episode of Dallas, "Guilt and Innocence," marked the beginning of Emma's (Emma Bell) transformation into a rebel, and costume designer Rachel Sage Kunin made sure her costume showcased the pivotal moment. "Emma is transitioning from a sheltered good girl into a rebellious character who has a few crosses to bear," Sage Kunin explained to InStyle.com. "This cranberry, short-sleeve fitted sweater was an intentional choice to start showing off a more alluring side. As Emma comes into her own, clothing will reflect those changes." We can't wait to see what she wears next! Click for more looks from last night's Dallas.
