This is the outfit that was worn by Sara Tancredi, played by Sarah Wayne Callies, in the Season 5 episode "Behind The Eyes" (5.09). It consists of a blue shirt and black pants (jeans). Why is it screen matched? The word "Hero" in written inside the jeans, which means that Sarah was wearing them and no one else. It also came with the wardrobe department tag detailing all the scenes it was worn in.
