COS’s Sweater Is on the Lyst Index: Here’s Where to Shop It

One brand that’s been on every fashion person’s lips this year is COS—and rightfully so. In 2025, the Swedish brand experienced significant growth and success. It returned to New York Fashion Week for a fourth straight season with a see-now, buy-now collection, tested pop-ups in Europe and Korea, and consistently launched collections that are modern, timeless, and wearable. It has now become the third hottest brand, behind Saint Laurent and Miu Miu, according to The Lyst Index Q3 2025 Report. To top it all off, its Chunky Cashmere Sweater was one of this quarter’s hottest items.

Of course, a cashmere crewneck sweater isn’t new, but COS’s version feels fresh and modern. Unlike other styles, it features a chunky ribbed collar design with matching ribbing on the cuffs and hem. The drop shoulders and oversize fit—two small details that many brands struggle to perfect—give it an effortlessly chic look. It’s available in a variety of neutral colors such as navy, black, gray, and beige, as well as muted shades like pale pink and pastel yellow.
