Since the marriage of Princess William and Kate Middleton, Prince and Princess William of Wales have been given a royal dukedom by The Queen and are to be known as the Duke and Duchess of Cambridge.
Catherine will be known formally as Her Royal Highness the Duchess of Cambridge. Her other name, as the wife of Prince William of Wales, the Duke of Cambridge, will be Princess William.
She was not born a princess so she is not (yet) Princess Catherine.
When the current Prince of Wales (Prince Charles) ascends the throne upon the death of The Queen and becomes King Charles III (or perhaps King George VII), the Duke and Duchess of Cambridge will become the Prince and Princess of Wales as well as Duke and Duchess of Cornwall and Lord and Lady of the Isles... at this point Catherine will become HRH Princess Catherine of Wales.

Unless Prince William granted a peerage on marriage, she will be Princess William - just as the present Duchess of Gloucester was "Princess Richard" before the death of her father-in-law and the wife of Prince Michael of Kent is "Princess Michael." So she will be Her Royal Highness Princess William of Wales.Diana Princess of Wales was never "Princess Diana," no matter what the press called her. At the time of her marriage, she became HRH The Princess of Wales; after her divorce, she was Diana, Princess of Wales.

Diana was called Princess of Wales because she was married to the heir to the throne of England
The Duchess of Cambridge's dress was designed by Sarah Burton, the principal designer at the House of Alexander McQueen. Also, may I point out that Catherine's title is NOT Princess Catherine. She can be called either Princess William of Wales OR The Duchess of Cambridge.
