Claudia Winkleman Just Wore the £50 COS Knit I've Loved for Years—And It's Still In Stock
A polished, practical staple with celebrity approval—Claudia Winkleman’s COS top is about to sell out again.


If, like me, you’re settling in every Wednesday and Thursday for the latest twists and turns in The Traitors, you’ll also be tracking Claudia Winkleman’s impeccable Traitors style. Each episode brings a new standout look—a dramatic cape here, a perfect knit there—that has me (a Gen Z) asking the same thing every week: where can I get that? That’s the power of Claudia. And, her ability to blend high street with luxury never fails to dissapoint. So when she layered a silk Alexander McQueen blouse over the COS Merino Wool High-Neck Top in a recent episode, I immediately took note.
It was the kind of styling move that proves why Claudia’s outfits resonate so much: chic, clever, and quietly practical. And truthfully, her choice didn’t surprise me. The COS Merino Top has long been a fashion-editor favourite—a foundation piece that consistently sells out each winter. The 100% merino wool feels luxuriously soft against the skin, the fit is close but comfortable, and the fine knit is thin enough to layer without adding bulk.
Of course, this isn’t the first time Winkleman has mixed high-end pieces with more attainable buys. From her cult-favourite Spanx leggings to her now-iconic red fingerless gloves from Amazon, it’s no surprise that her signature style continues to resonate. With stylist Sinéad McKeefry behind the looks, each ensemble strikes that familiar Claudia balance—slightly mysterious, effortlessly chic, and perfectly attuned to the moody Scottish backdrop of the show.
