ISO!! SEARCHING for Catherine Malandrino Cardigan!

DO NOT PURCHASE! I DO NOT HAVE THIS ITEM! Hi there! I'm in search of this striped cardigan/sweater by Catherine Malandrino in a size medium (first choice) or small (depending on the fit/length). It was worn on the show Pretty Little Liars on the character Aria Montgomery! If anyone has or knows where I can get/find it, I would greatly appreciate it!
