As the gripping new series of The Traitors returns to our screens in January 2026, the spotlight isn't solely on the roundtable betrayals. Once again, presenter Claudia Winkleman's impeccable wardrobe is generating almost as much buzz as the gameplay itself. This season, set against the chilly Scottish backdrop, a particular £45 high street staple has been revealed as Claudia's secret weapon against the cold.
The High Street Hero: A £45 COS Polo Neck
The item causing a stir is a sleek, high-neck polo top crafted from merino wool. Far from a luxury designer splurge, this essential layer is from the accessible high street brand COS. Available in several shades and featuring a slim, flattering fit, it's the perfect insulating piece for the show's frosty filming conditions and a versatile addition to any winter wardrobe.
The details were confirmed this week when Claudia's stylist, Sinead McKeefry, shared the exact top on her Instagram Stories. This sent legions of style-conscious fans straight into shopping mode. Sinead is renowned for her expert mix of accessible brands and unique British finds, a styling philosophy that has become integral to the show's visual appeal.
Why Merino Wool is a Winter Winner
The choice of material is key to this top's success. Merino wool is exceptionally warm due to its natural crimp, which creates tiny air pockets that trap body heat. However, it's also breathable, moisture-wicking, and excellent at temperature regulation. This makes it ideal for fluctuating environments, whether on a Scottish estate or moving between the cold outdoors and heated interiors, preventing that uncomfortable sweaty feeling.
More Affordable Gems from Claudia's 2026 Wardrobe
Just a few episodes into the new series, other affordable fashion pieces from Claudia's wardrobe have also captured attention. For the opening episode, she opted for a sophisticated velvet burgundy blazer from Reiss, currently on sale for £138 and nearly sold out.
She paired it with a delicate tie-neck blouse from LK Bennett, chosen in a soft pastel pink. Crafted from viscose and featuring pearl button details, this blouse adds a touch of refined elegance. It remains in stock in all sizes from 6 to 20, offering viewers a direct route to emulate Claudia's polished on-screen style.
Claudia Winkleman's continued championing of high street and accessible brands demonstrates that standout television style doesn't require a fortune. Her £45 COS merino wool top is a testament to smart, sustainable layering—a practical and stylish buy that promises to be a winter favourite for years to come.
