What tipped it off for me was, when I first clicked this thread I did a search for her dress so I could vote in the poll.
What struck me was how many photos there were where she was just not smiling. She looked downright unhappy. And event the ones where she was, it looked forced.
Her lips smile, but it never reaches her eyes.
I had no knowledge of the backstory. All I could think is: What is up with that?
