I think Camilla had the right idea to make sure she was attending a school's Harvest Festival, far more important. Probably arranged after the thought of not be able to leave the church once the bride had arrived. If this is a problem for you, you are advised to wear a nappy!!
Not that I'm suggesting she is incontinent lol! It would be enough to put me off from going, I wouldn't be able to think about anything else.
Just seen Eugenie on the news, she looked lovely, beautiful dress.
