Earlier today, at an engagement with the Royal Air Force Air Cadets in Stamford, England, the Duchess of Cambridge debuted one of her most fashion-forward daytime looks. The military-influenced jacket from Philosophy di Lorenzo Serafini seemed to be a stylish sartorial allusion to her surroundings. Letting her jacket take the lead, Middleton offset the bold hue with a simple turtleneck, coordinating skinny jeans, and Stuart Weitzman to-the-knee boots.

Middleton is all about the details, and her ladylike gloves were an ideal way to punctuate her “Duchess off-duty” style. Along with Middleton's embrace of forward-thinking designs from Alexander McQueen, Barbara Casasola, and Preen by Thornton Bregazzi, this was yet another example of the Duchess adapting her fashion mindset to the demands of everyday dressing.
