The Duchess of Cambridge attended the National Portrait Gallery on Wednesday 4 May for the unveiling of her portraits.
The images of the Duchess, taken from the latest issue of Vogue magazine, were the latest prints to be added to the 'Vogue 100: A Century of Style' exhibition.
Vogue's exhibit showcases the range of photography commissioned by British Vogue since it was founded in 1916, to mark the magazine's 100th birthday.
The new cover featuring the Duchess of Cambridge appears on the official centenary issue.
To mark the occasion, the Duchess wore a pale pink Alexander McQueen peplum dress - one she first debuted in 2014 on the Royal Tour of Australia - teamed with a glittering Monica Vinader diamond necklace and matching earrings.
Back in 2012, she became patron of the National Portrait Gallery and the following year a portrait of her by Paul Emsley was installed in the primary collection, where it still hangs today.
