Last night's Pretty Little Liarsfinale was epic! Not only did we (maybe) learn that the "late" Alison DiLaurentis (Sasha Pieterse) is alive and well, but also that she might also be the infamous scarlet trench-lover, Red Coat. (Gasp!) But then we hopped on the phone to talk to costume designer Mandi Line, and she said we shouldn't be too sure just yet. "We know that Red Coat is a female, because the writers just gave me the go-ahead to let her wear heeled boots," said Line. But didn't Spencer (Troian Bellisario), Hannah (Ashley Benson), and Mona (Janel Parrish) see Alison last night? "Maybe! Wait until you see the episodes coming up, though—it could go it any direction!" And for such an integral character, Line had to pick just the right cherry topper. "I didn't want it to be too tailored, and I wanted it to drape nicely, so it had a little swing [when she walked]," said Line. "It couldn't be too fashionable. It had to be able to take on [the action scenes]. Plus, I wanted it to be a nice blue-red, so it would complement a number of skin tones." A number of potential A's! Find out who's who when Pretty Little Liars returns this June.
