Kate Middleton in a cream dress in her latest engagement.

Kate Middleton wore cream, or basically white, after Labor Day. The duchess shared photos on Instagram (opens in new tab) of a recent event celebrating her photography project Hold Still (opens in new tab). On the day of the event, Middleton (open in new tab) wore a self-portrait (open in new tab) cream dress with a built-in belted blazer and a delicate chiffon and lace midi skirt. She wore her hair in a perfect ponytail, showing off statement earrings and a delicate necklace.

She captioned the post, "Thank you to my amazing partner for making hold still a reality."

"It took a long time for all the people behind this amazing project to actually come together, but tonight we finally did it...The idea for HoldStill2020 was born at the same time the pandemic began, using the amazing power of photography, It was intended to bring people and communities together. [What's even more amazing is how it was all planned out, from the kitchen table to the spare bedroom.

"Special thanks must be given to the thousands of people across the country who took the time to share their experiences of confinement. Without them, this project truly would not have been possible.

Fans congratulated her on the project and commented on her flawless outfit: "She was beautiful as always.

"Princess Catherine is fabulous, as always! So proud of our future queen," wrote another.

This new fashion rule-breaking incident occurred after Middleton wore skinny jeans (opens in new tab) in bold defiance of the Gen-Z style code (opens in new tab) during a visit to the Lake District in England. There are no rules in fashion.
