Like looking rich? Then pay close attention to what I’m about to say next. Sweater season is upon us, which means that we’re revisiting our knitwear collections and maybe even shopping for a new style or two. I love a classic plain sweater as much as the next person, but it’s already clear that the styles and silhouettes that will contribute to the most expensive-looking outfits of fall and winter 2025 involve one of a few specific sweater trends. And no, they’re not your run-of-the-mill crewneck styles.

Four sweater trends have emerged as the major styles to know. From the fall 2025 runways to the feeds of the coolest It girls, I’m already seeing these trends take over. Surprisingly, argyle is among them, in no small part because of Khaite’s cosign. V-necks are another trend that’s coming back this season for the first time in a while, but in a modern way with subtle high-V necks. Fair isle knits tap into an après-ski vibe that will transport you to the slopes of Gstaad or St. Moritz. Lastly, polo sweaters are tapping into the preppy aesthetic that’s been on the rise all year. Here, discover the four most expensive-looking sweater trends of fall 2025 and shop the most buy-worthy versions of each.

Argyle Sweaters

When I attended the Khaite show in February, I was surprised to see several argyle sweaters in the collection, but as is usually the case with the runway, it wasn’t until the fall actually arrived six months later that the knits made more sense. Now, I’m noticing the academic theme everywhere I look and I’m convinced it’s one of the major sweater trends to know.
