Kate Middleton Is An Alexander McQueen Dream In The White Blazer Dress She Wore To Trooping The Color—Simply Stunning!

Kate Middleton has been celebrating Queen Elizabeth II‘s 70-year reign in style! The Duchess of Cambridge, 40, arrived at the Platinum Jubilee’s Trooping the Color event in an exquisite white blazer dress by Alexander McQueen that featured a cinched waist and elegant long sleeves.

With this item, Middleton paired a blue-and-white Philip Treacy hat to shield from the sun as she stood with her family on the iconic Buckingham Palace balcony.

Middleton is no stranger to rocking Alexander McQueen, as she has previously donned pieces from the luxury brand to past Trooping the Color events and elsewhere.

For this year’s ceremony (which marked the official birthday of the British Sovereign), Middleton opted for this crisp white dress and accessorized with captivating sapphire and diamond dangly earrings. This style choice, of course, paid homage to her late mother-in-law, Princess Diana, who previously owned the jewelry. (So sweet!)

The Duchess wore her long brown locks into a glamorous chignon updo and added a sparkling silver necklace with a heart-shaped charm to complete her look. Along with her husband Prince William, 37, and their children Prince George, 8, Princess Charlotte, 7, and Prince Louis, 4, she waved to onlookers and gathered with family for the special day that honored the monarch, 96, and her 7 decades on the throne.
