I Just Saved $1200 By Shopping This TikTok Viral COS Sweater

As a fashion editor, I must admit, I love a good deal.

But it can't just be any type of run-of-the-mill deal. I'm talking about the kind shopping steal that hits that rare sweet spot between quality, cut, and price. The kind of deal that feels like a secret handshake between fashion insiders. So when fashion TikTok began buzzing about a certain COS cashmere sweater, likening it to a very high-profile designer version that’s quietly sat at the top of every fashion person’s wishlist, I dropped everything to investigate. Frankly, I had to see what the hype was about.

Spoiler: the hype is very, very real for the COS Chunky Pure Cashmere Crew-Neck Sweater.

Technically, I ordered the navy version online the moment I saw it—but my patience lasted all of 36 hours. The buzz was too loud and the stakes were too high, so a few days before my package was even set to arrive, I made a beeline to the COS store in SoHo on my lunch break, hoping to try it on in person. Fashion emergencies happen, and in this New York City, same-day gratification is a luxury of its own.

Hanging on the rack, the COS Chunky Pure Cashmere Crew-Neck Sweater in Beige immediately stood out. There’s a noticeable difference when cashmere is actually thick—the weight, the plushness, the drape. This wasn’t the flimsy, borderline see-through cashmere you often find at lower-price points (of which my closet is already filled with.) As a cashmere snob, I have high expectations and, with the last sweater in my size hanging discreetly at the back of the rack, I made a beeline for the fitting room.
