The Sultan of Oman, Sultan Haitham bin Tarik, started his official state visit earlier today, and that too, at his own residence in London. This is where Prince William welcomed him on behalf of King Charles. The Prince of Wales also shook his hand, while having a rather engaging conversation with the Sultan. Following this, he also took his highness to Windsor Castle to meet the King, Queen Camilla, and Princess Kate, who curtsied beautifully as she officially welcomed him. She opted for a spectacular forest green-hued long coat dress, crafted by Alexander McQueen for the occasion. But that’s not all; Kate also managed to wrap up the super busy day by making heads turn in an incomparable look for the grand banquet.

This grand evening was hosted at Windsor Castle by the King in honour of his esteemed guest. For this star-studded and red-carpet-ready occasion, the Princess of Wales opted for a bright yellow-hued gown, which was designed by none other than Elie Saab. The gasp-worthy gown, with an attached cape, moved gracefully as the beloved Princess walked ahead with charm and grace. The simply spectacular gown also had a fabulous keyhole neckline, adding some modern charm to the otherwise formal ensemble.

Furthermore, the future Queen also left her beautiful brunette locks open and styled into the most gorgeous waves. They added some extra charm to her ensemble. Even her makeup was exactly on point, with the prettiest neutral lip shade. Beyond this, Middleton also added some extra wow-factor to her look with the prettiest accessory choices. This included diamond-encrusted dangling earrings with a matching necklace, stylish heels, and a matching clutch, which really rounded out the whole look. However, her tiara was the element that stole the spotlight. After all, this was the Princess’ favorite, the Queen Mary Lover’s Knot Tiara.

This isn’t only the future Queen’s go-to choice, but according to reports, it also happened to be Princess Diana’s favorite choice. The former Princess of Wales was often seen wearing the tiara throughout her royal life. With this choice, Middleton actually paid homage to her late mother-in-law, making the evening extra special. In fact, this wasn’t the first time that the Princess paid a tribute to Diana. She also wore Diana’s brooch earlier in the day, leaving every onlooker gushing and gasping. Ultimately, it’s also safe to say that this outfit highlighted Middleton’s ability to blend royal tradition with modern elegance, creating a rather memorable ensemble.
