Right from the very start, every possible negative photo was syndicated by the press. I am sure that Diana showed a bit of leg getting out of a car every now and then, had the wind catch her clothes, but we never saw these, but we did of Sarah. Every time she put on a lb or 2, and her dress was a little tight, there was the press comment. She did not get any of the support that Diana did. The pattern repeated with Megan (not that I like HER one bit, but we do seem to love the heir and denigrate the spare).
She was part of a social set that included him - what he did was not her fault, was not in her ken.
