It's Official: These Are the 13 Most Popular COS Buys of 2026 So Far

It seems like sporty yet chic dressers everywhere are wearing fleeces with leggings and tailored pants. This elevated version hits on the sporty-retro vibe while remaining modern and tasteful thanks to the luxe boiled merino wool, mock neck, and neutral hue. Note that this piece also comes in a gorgeous chocolate brown.

This new classic T-shirt is the ultimate wardrobe staple, serving as the grounding element that ties everything together. It's made from an organic cotton jersey fabric that gives it a weighty feel, yet it retains a clean fit and a long enough hem to be tucked into mid-rise trousers or left hanging out.

I'm predicting that COS has another viral hit on its hands with this mock-neck knit, following the immense popularity of its Chunky Pure Cashmere Crew-Neck Sweater, which even made the Lyst Index last year. This new version, which is already sold out in ivory, shares the same material, weight, and ribbed hem as the original crewneck. The key difference is the chunky ribbed high neck, which elegantly frames the face. For the most stylish finish, try tucking your hair into the neck to achieve the coveted Olsen tuck.

While trouser silhouettes may be narrowing in 2026, the baggy fit remains a perennially cool choice. This particular style, a new addition to COS's winter collection, features a loose cut that gently tapers to the ankle. Details include three pleats, a single back pocket, and a concealed hook-and-eye closure. Choose between the navy and the black, and style it with a fitted blazer, sheer tights, and heeled sandals.

While blanket scarves are cozy and charming, a cashmere triangle scarf—particularly one in a vibrant color—offers a sleeker, more refined look, especially when layered over an oversize jacket or coat. Though several brands offer this style, the version from COS has proven the most sought-after, selling out every time it's been replenished. Don't miss this opportunity to grab it now that it's back in stock.

At first glance, this sweater appears simple, but upon a closer look, it boasts several sophisticated details. Notable features include double-knitted shoulders for added dimension without bulk and a raw rolled hem that contributes to its relaxed aesthetic. Plus, it is crafted from soft merino wool, ensuring a lightweight layer that drapes nicely.

Remember that stunning navy coat from COS's F/W 25 runway? It has finally launched in navy and brown and is already selling out. Fashion insiders are drawn to its unique silhouette, which includes a subtly fitted waist for shape and an oversize collar that offers an organic touch whether styled open or closed.

The Dial Jeans are a favorite for their wide-leg silhouette and organic raw denim that gives it a rigid look. While these pants were first released in light beige and black, they now come in a dark-blue wash, catering to those who have or want to invest in the hottest denim color trend for 2026.

A wool jacket is a key piece for transitioning between seasons, easily adapting from winter to spring through layering. Selecting the perfect one is crucial, as it offers significant versatility and wear. This COS style is a smart investment that features fabric-covered buttons and a nearly collarless design. For a chic look, wear it over a white button-down with an interesting neckline, then complete the outfit with baggy trousers and loafers.

When it comes to wardrobe basics, I always recommend polo shirts. Specifically, I suggest opting for half-zip polo tops over traditional button-downs. The half-zip style feels more modern and less preppy, which is great if that's not your usual aesthetic. I particularly like layering them under crewneck sweatshirts and pairing them with baggy trousers and sleek sneakers.

If I were in the market for a new pair of pants, these would be the ones. The high waist and straight leg make them an instant staple. It goes without saying that they pair well with all types of tops and outerwear, but they also work with all shoes, which is hard to find in a pair of pants.

High-vamp heeled pumps that cover the middle of the upper foot have been a major trend for the past five months. However, as we transition into winter, I anticipate a shift toward high-vamp heels that come up a bit higher, hitting just below the ankle. This style is inherently elegant, whether paired with a midi skirt to reveal a sliver of ankle or worn with jeans, allowing only the shoe's toe to peek out.

Don't sleep on COS's handbags. Just like its knits, pants, and outerwear, the brand makes amazing bags that fashion insiders covet every season. In the fall, it was the Mini Studio and Marais Bowler Bags. This winter, it's shaping up to be the Knoll Shoulder Bag, which has a very relaxed vibe thanks to its slouchy suede fabric and long strap. Stuff your essentials in it, then sling it over your shoulder whether you're heading to Pilates or the office.
