There were fears that she would 'upstage' the nominees of the 70th annual EE British Academy Film Awards in London.
But the Duchess of Cambridge successfully championed understated glamour for her red carpet appearance, naturally arriving fashionably late alongside husband Prince William.
The last to arrive, despite being just a short drive away from their Kensington Palace home, William and Kate were met by loud cheers outside the Royal Albert Hall.
Kate looked every inch the best dressed attendee in a bespoke off-the-shoulder Alexander McQueen gown.
The dress was cut in a drop-waist style and covered in a delicate floral pattern.
She wore her hair twisted into a chic up-do, allowing her to show off large, sparkling chandelier earrings.
Have a look at the photos above, and let us know below what you think of the gown!
