he Erdem Pre-Fall 2023 Ottoman jacquard peplum jacket and matching skirt was accessorized with a Sean Barrett hat

Negative fan comments criticized the outfit's print, color, silhouette, and aging effect on Kate.

Positive fan responses appreciated the outfit's breathtaking regal look, old Dior atmosphere, Kate's style risks, and new, exquisite appeal.

Some thought the mismatched blues didn't work, while others thought the outfit had too many shades of navy.

The hat was also criticized, with some suggesting a white hat would have been better.

Many wondered why the clothing was so hated and felt Kate looked gorgeous and regal nevertheless.

Kate's stylist was even called to be fired by one fan.

The outfit was seen as a clever decision as the designer, Erdem Moralıoğlu, was born in Montreal, which has ties to the Commonwealth.
