If there's one thing most royal fans look forward to, it's seeing their favourite royal ladies in a sparkling tiara!
There have been a number of formal occasions when the Duchess of Cambridge has popped on her very own piece of diamond headwear – and she always looks magical.
We don't often see Kate wear a tiara – the exclusive accessories are saved only for state dinners and receptions at Buckingham Palace, and of course she wore a tiara at her royal wedding to William back in 2011.
