FWIW Robyn was not wearing the same dress two days in a row.
(in reaction op various posts in the thread before this one)

Noticed something about a week ago, so asking if anyone else did. Only speculation, asking a question, IMO.:
As they are leaving the restaurant, Robyn appears to be looking to the right, while GG appears to have his upper body turned forward and appears to be looking forward.
There is a car parked immediately in front of them. From what I can see, there might be one of those silver windshield heat shields on the dash (I could be totally wrong, though). If there was a heat shield in the windshield, do you think it might be possible that someone could have been sitting in that car watching them? If so, Robyn probably wouldn't have noticed since her line of sight seems to be towards the right.
