Alexa’s Clever Layering Trick Just Made Denim and Knitwear Feel Impossibly Cool

By Swedan MargenDecember 10, 2025

It’s chilly outside, and staying warm without piling on endless layers of knitwear is no small task. Determined to keep cosy without disappearing under a mountain of wool, I’ve been re-learning the art of clever layering—and naturally, Alexa Chung is leading the lesson.

Demonstrating exactly how it’s done, the model and presenter built a cosy look from the foundation up. She began with a chin-skimming white turtleneck—fresh, bright and the perfect blank canvas. Rather than stopping there, Alexa locked in warmth by adding a classic crew-neck cardigan over the top. With the turtleneck subtly peeking out, her simple two-piece styling formula added instant depth and dimension in the easiest way.

She then completed her outfit with a pair of deep-indigo dungarees and black, rounded-toe heeled boots, styling her navy cardigan buttoned right to the top—save for the highest button she left undone to reveal an intentional flash of white beneath.

Rather than reaching for a slouchy jumper and stopping there, this clever knitwear combination worked extra hard to elevate her casual denim, giving the look more structure while maintaining a sleek silhouette that would style neatly under a heavy winter coat.
