Don't Even Think About Wearing a Sweater Unless It's One of These "Rich" Trends

By Kevin Harson9 November 2025

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.

Khaite

Anders Argyle-Knit Cashmere-Blend Top

I love the combination of burgundy and light blue here.

Reformation

Cove Cashmere Oversized Crew

This looks like a sweater I'd absolutely live in.

J.Crew

Perfect Cashmere Crewneck Sweater in Argyle

Gap

Cashsoft Crop Cardigan

Easy (and currently on sale).

High V-Neck Sweaters

Crewnecks are no longer the default neckline. Fashion people are are instead reaching for sweaters (and T-shirts and dresses too, for that matter) with a high V neckline. If you ask me, a high V-neck sweater is the easiest way to make your fall outfits look current. Bonus points if you layer it over a white T-shirt.

Gap

Cashsoft Oversized V-Neck Sweater

People like to rave about how good Gap's cashmere sweaters are.

Amiya

Nevia V Neck Sweater

The color, the shape, the ribbed hemline—this sweater is a perfect example of why new knitwear label Amiya is one to know.

The way it cinches at the waist is so good I almost stood up and applauded.

AFLALO

Elara Sweater in Cashmere

The label where all the cool New Yorkers are getting their sweaters this season.

EDIKTED

Oversize V-Neck Sweater

Nordstrom

V-Neck Cashmere Sweater

Nordstrom cashmere is truly top tier.

ZARA

100% Wool V-Neck Sweater

Okay, creative styling idea!

Polo Sweaters

With preppy style coming back in full force, polo sweaters are once again at the top of the pile. Whether you opt for a thin and fitted polo knit top, a relaxed-fit style, or a striped rugby polo, the collared silhouette immediately adds an air of East Coast prep—and a certain "old money" vibe that looks so expensive.

COS

Cornflower Blue Sweater

This shade of blue, though.

Leset

Jesse Wool Polo Sweater

How adorable are the tiny buttons?

Almina Concept

Polo Wool Sweater

If you know me, you know I'm a huge fan of Almina Concept sweaters.

ZARA

Plain Knit Polo Shirt

The elongated buttons make it a touch more elevated.

Fair Isle Sweaters

Finally, we have fair isle sweaters. Whether or not you like to ski, these knits will have you tapping into the ultimate après-ski mood and looking like you're fresh off the piste in Gstaad or St. Mortiz. Designers like Altuzarra are putting a fashion-person spin on the alpine style and we've already seen the style set begin to embrace fair isle this season, which means the style is only going to grow more popular as we near the holidays.
