Elevate your downtime with this pyjama shirt, which is crafted from premium 100% mulberry silk and jacquard-woven with a geometric motif – look closely and you'll see that the COS logo is subtly nestled within the shapes. It's cut in a relaxed shape and has a camp collar, dropped shoulders and a patch pocket at the chest. Wear it as a set with the coordinating trousers.
A brand whose aesthetic has been so influential that it’s hard to remember what went before. But when COS launched in 2007 against a backdrop of fast, trend-led fashion, its focus on minimal pieces at accessible prices was a breakthrough moment. With a focus on style over trend, it heralded a new era for interesting, modern, considered design and changed our wardrobes for the better, forever.
