The Princess of Wales kicked off the garden party season on Friday afternoon to co-host the famous Buckingham Palace event on behalf of King Charles with her husband, Prince William.
The royal couple looked incredibly stylish in their finest attire, and it was exciting to see Kate donning an all-new outfit, as opposed to a recycled garment.
The mother of Prince George, Princess Charlotte, and Prince Louis donned a white blazer dress by one of her most-worn brands, Self-Portrait. It was crafted with a gentle peplum, and the double-breasted number was finished with three-quarter length sleeves and a Carrie Bradshaw-style corsage at the bust. This looked wonderful teamed with the lightly pleated midi skirt, adorned with polka dots, which was expertly attached.

The website said of the style: "A polka dot print skirt brings light-hearted ease to this tailored midi dress. The cream wool top boasts an elegant flower corsage and suits-all square neckline – add heels for trips to the opera."

It appears that the royal made this simple change to her look, which is in keeping with her signature style.

The royal looked stunning in her cream gown, made especially for her. It featured a standing collar, short sleeves, and a belted waistline. The designer number also boasted the most romantic pleated skirt and a set of utility pockets down the bodice for a modern touch.
Princess Kate-style blazer dresses
A blazer dress with a contrasting skirt is such an elegant ensemble that's perfect for a formal occasion where you want to appear elegant and well-presented.
This belted midaxi dress from Very has a hugely similar silhouette to Kate's dress, and this polka dot number by Joe Browns features the same polka dot skirt, with a black tailored blazer instead of white.
Kate's Self-Portrait support
The wife of Prince William has always loved wearing ensembles by UK-based brand Self-Portrait. The label boasts an A-list clientele, including Beyoncé, Reese Witherspoon, Kristen Stewart, and Miranda Kerr. It was founded in 2013 by Malaysian-born designer Han Chong, and its headquarters are based in London.
