Kate Middleton 's 'favourite' tiara is known for "terrible headaches", a royal expert has revealed.
One of the Princess of Wales' "firm favourites" of stunning tiaras that have been passed down to her from the Royal Family is reportedly not as comfortable as it looks.
While the Royal Family own an array of glitzy and extravagant tiaras - which have been passed down and shared by different generations of women in the monarchy - Kate's favourite was also owned by Princess Diana, the former Princess of Wales while she was married to the now- King Charles II.
