That yellow shirt. Every diehard Pretty Little Liars fan knows exactly which shirt we're talking about. We've seen that shirt multiple times through our flashbacks to Ali's wild and dangerous night, and star Sasha Pieterse is ready to say goodbye to the frilly mess. "Mandi Line, our costume designer, didn't pick it," the star defended. "We had a different costume designer when we did the pilot, and [Mandi has] often said, we will burn that shirt eventually." Since Sasha has been put in and out of graves multiple times throughout the series, the iconic yellow shirt has had to be duplicated. "It got dirty with me coming out of the grave," the star explained. "So now there are 13 yellow shirts floating around." Agghhh! They're multiplying!
