You are quite right - very few women are virgins on marriage and still wear white but there was a lot of press around at the time, with “sources” claiming that it was exactly for the reasons as I set out that the Queen was unhappy.
Remember, she refused to go to the King's wedding when he remarried and the Princess Royal went to Scotland to get remarried and the Queen didn’t attend.
The Queen was a very devout woman and took her rôle as Defender and Protector of the Faith and Supreme Head of the Anglican Church very seriously.
She refused to allow her own sister to marry a divorced man and told Princess Margaret that she must choose between love and the Royal Family. Ultimately the Princess chose her family and duty.
I think because a lot of people aren’t as caught up in the religiosity of the Church as much as they were in the past, they don’t perceive things like being divorced as a big deal, but for a woman whose family had already been through the wringer of scandal with the abdication and who was brought up to put duty first, being divorced, wearing white, having a veil, were all a big deal, as it just wasn’t right (in her eyes).
