Camilla's full titles (but not styles) after her marriage are
Her Royal Highness The Princess of Wales and Countess of Chester, Duchess of Cornwall, Duchess of Rothesay, Countess of Carrick, Baroness of Renfrew, Lady of the Isles, Princess of Scotland.
Clarence House has indicated that when Charles accedes the throne it is intended that she will use the title HRH The Princess Consort, although, as with the example of the Princess of Wales, technically as the wife of a King, Camilla would be Queen.
