Washington: Just like all of us, even celebrities have their favourite outfits and accessories they swear by for a special occasion. The Duchess of Cambridge, too, has her own sets of favourites and for the state dinner at Buckingham Palace, she wore one of her go-to tiaras. \r\n\r\nMiddleton arrived for the state banquet for President Donald Trump, who is on an official visit to the UK, wearing her favourite Lover's Knot tiara paired with the Queen Mother's sapphire and diamond fringe earrings for the dinner, reported People.\r\n\r\nMiddleton also wore a blue, red and white sash of the Royal Victorian Order on her shoulder over her stunning white Alexander McQueen gown, marking the first time ever she has worn the new honour. It was gifted to her by the Queen for her eighth wedding anniversary in April, this year.\r\n\r\nShe attended the event alongside her husband Prince William.\r\nMiddleton was last seen in the Lover's Knot tiara at the Queen's state banquet in October, last year for King Willem-Alexander and Queen Maxima of the Netherlands.\r\n\r\nThe Lover's Knot tiara often referred to as the Cambridge Lover's Knot is a beautiful pearl-encrusted tiara that is one of the most famous in the British royal family's collection. It was also a favourite of the late Princess Diana. William's wife also wore a pair of pearl drop earrings, which also belonged to Diana.\r\n\r\nPresident Trump, First Lady Melania Trump, and his children were hosted in the ballroom. The horseshoe-shaped table decorated with vast pink-themed floral arrangements was laid for the guests.\r\nTrump's children Ivanka Trump, Donald Trump Jr., Eric Trump, and Tiffany Trump also graced the event. Ivanka sat next to Sophie, Countess of Wessex, and her husband, Jared Kushner, was with Princess Anne for the dinner.\r\n\r\nOther guests included the Marchioness of Cholmondeley and her husband, who's titled the Lord Great Chamberlain -- Norfolk neighbours of William and Kate who made headlines recently for an alleged feud between the two couples.\r\n\r\nTrump and Queen made speeches, each reflecting on their countries' shared history, common values and the significance of a continued alliance.\r\n\r\nPrior to the banquet, the Queen hosted a private lunch for Trump and his wife. Later, the President and First Lady joined Prince Charles and Camilla, Duchess of Cornwall for tea at their nearby residence, Clarence House.\r\n\r\nPrince Harry attended a private exhibition without his wife Meghan Markle, who is currently on maternity leave after giving birth to their son Archie Harrison on May 6. The couple is said to be making their first joint appearance since their newborn's birth at the annual Trooping the Colour celebrations in honour of the Queen's birthday this Saturday.
