Well,
@MassGuy, I listened to the early SS interview video from Thread 1 (reposted today on T3) and SS clearly states that KR did change her pants. In the 6ish pm store image, KR is wearing blackish pants. And SS told her interviewer, when he asked, that KR changed into green pants for the party. She does not say why, but it doesn't matter I suppose. SS also confirmed that KR's belt and top were the same from earlier to later. Therefore, the one photo released by LE does not show the actual clothing KR was wearing at the party, per SS. Perhaps just a technicality, but all the details matter, right?
