Camilla on her wedding day to Charles

The late Queen warned daughter-in-law Camilla not to wear her elaborate feathered headpiece which nearly blew away at her wedding to Charles. Camilla famously battled the wind to keep her headpiece in place as she and Prince Charles emerged from their civil marriage ceremony at Windsor Guildhall. MailOnline can now disclose that she had frantic words with Charles on the steps of the hall, telling him of her fears that her feathers might fly away. Details of their conversation emerged after a MailOnline lipreader viewed film of the couple's wedding on April 9, 2005, and worked out what they were saying. Analysis of the footage also revealed for the first time that the late Queen waded into the discussion and told her son: 'I did warn her, wearing feathers.'
