It was the centre piece of the King and Queen of Spain's official visit to the UK, but the Duchess of Cambridge couldn't help but steal some of the spotlight at last night's decadent state banquet held in the Spanish royals' honour.
The glittering event took place in Buckingham Palace, where Her Majesty the Queen hosted King Felipe VI and his wife Queen Letizia along with the rest of the royal family. In honour of the visiting Spanish royalty, intricate sugarwork red carnations - the national flower of Spain - adorned gold plates througbout the banqueting hall, and candles were lit on gold candelabras.
Along with the Duke and Duchess of Camrbridge, Prince Charles and Camilla, Duchess of Cornwall were in attendance, as well as Prince Harry.
Despite her attempts to remain in the background and away from photographers, the Duchess of Cambridge couldn't help but turn heads in a beautiful dusky pink, floor-length lace gown with fluted sleeves. The gown, which also featured a daring plunging neckline, was by designer Marchesa.
To complete the glamorous look, the Duchess of Cambridge once again borrowed a set of opulent jewels from the Queen herself. The perfect accessory for her dress, the Duchess wore the Queen's diamond and ruby necklace and a pair of pearl drop earrings.
The necklace has very special significance to the Queen, as it is actually a prized family heirloom that was given to Her Majesty by her parents as a wedding gift. The exquisite piece of jewellery was originally owned by the Queen Mother, whose friend Margaret Greville first bought it in 1907 from jeweller Boucheron. The Queen wore the necklace many times in her youth, most notably at the Royal Variety Performance in Blackpool in 1955.
To complete the look, Catherine wore the infamous ‘Lover's Knot' tiara, which belonged to Princess Diana previously. The exquisite piece is said to be so heavy, that the Princess of Wales complained it gave her headaches when she wore it.
Fans were full of praise for Catherine's beautiful and elegant look, completed with heirloom jewels fit for a Queen.
Stepping back from the glare of waiting photographers, the Duchess of Cambridge did her best to ensure the guests of honour where the centre of attention throughout the evening.
Accompanying her husband King Felipe VI, Queen Letizia of Spain certainly turned heads in a regal crimson red ball gown. The stunning, embroidered floor-length dress was designed by Spanish fashion house Loewe, which is currently headed Irish-born designer Jonathan Saunders.
