Tuesday night's sparkling soiree was a regal one and the Duke and Duchess of Cambridge went all out for the occasion.
The royal couple arrived at Buckingham Palace for the Diplomatic Reception in their chauffeur-driven Bentley. How did they look? Pretty impeccable. Wills was dressed in his suit and bow tie, Kate wore a TIARA.
That's right, the Duchess wore a stunning tiara which had be loaned to her by the Queen and had belonged to Princess Margaret.
The beautiful headpiece (complete with diamond arches and pearl detailing) was the perfect accompaniment to Kate's diamond drop-down earrings and Alexander McQueen gown. The last time we saw her looking this radiant and regal was on her wedding day, but last night's state banquet was the perfect place to wear some serious sparkle.
Unfortunately, diamond tiaras aren't that easy to come by unless you're a duchess.
