That’s because this week sees the release of the British beauty's latest Topshop collection, and this time around it's sexier than ever.
Featured alongside statement dresses and jewelled knitwear is Kate's debut nightwear range.
Fashionistas can choose from silk pyjamas, lounge suits and luxe lingerie inspired, of course, by elements of the model's own highly sought-after wardrobe.
The collection itself – Kate's fourth for the high street chain - seems inspired by the Orient, combining bamboo and lotus flower prints with kimono-style sleeves.
First to fly off the shelves will, no doubt, be the pieces showcased by the lady herself in ad campaigns, including a daringly low-cut sequinned dress which is perfect for the festive party season.
So how does it feel to have women clamouring to pick up staples based on her wardrobe?
Admitting she occasionally feels "a bit reluctant to share my stuff with millions of people," Kate told the Guardian: "I'm not possessive. I'm caring-sharing."
The huge success of her collaboration with Topshop is a source of delight for the 35-year-old cover girl. But her greatest happiness is her little girl, Lila Grace.
"The thing I am most proud of is my daughter," she revealed. "She's seven now, and vice captain of her class! My goodness! I've never been vice captain of anything."
"She wants to be a chef, and her imaginary husband is a chef too. I was mother of the bride at their imaginary wedding, standing on the side holding her imaginary baby."
