In sharp contrast to the tailoring on the runway, Balenciaga's AW19 collection contains a few pieces belonging more to the loungewear category, including this elevated take on pyjama trousers. They're cut from soft checked cotton-flannel in a wide-leg shape and fitted with a flexible elasticated waistband. We won't recommend them for sleeping, but encourage you to wear them with some of the brand's chunky sneakers and an oversized tee or sweatshirt.
