The Ultimate Guide to Winter Sweaters: Styles, Fabrics & Trends

As the frosty winds of winter blow in, there's nothing like bundling up in a cozy, snug sweater. But then there's the age-old question: comfort or style? This winter, don't compromise on either! In this guide we'll cover the sweater styles and fabrics that are as beautiful as they are practical, the sweater trends worth knowing this season, and my favorite styling tricks to look chic and put together all winter long.

Four go-to sweater styles

When it comes to winter sweaters, there's a wide array of styles to choose from. When deciding which sweaters deserve a place in your closet, consider silhouette, fabric and personal style.

1. Classic knit

Classic knit sweaters exude timeless charm and femininity. Their simple, clean lines make them the perfect go-to for everything from work to play to holiday parties. Classic knits are perfect if you love a minimalist, comfortable style.

For a sweater with some visual intrigue, look for details like cuff buttons, turtleneck necklines or woven patterns.

2. Chunky cable-knit

Chunky cable-knit sweaters are all about texture and warmth. They usually come in oversized silhouettes, so pair them with slimmer bottoms like leggings, tights or straight-leg jeans for a chic, put-together look.

Chunky cable knits often have elaborate patterns that add texture, dimension and warmth. They have a rustic yet enduring vibe that works with all kinds of style aesthetics.

3. Turtlenecks

Turtlenecks are a modest yet alluring neckline. They're a great way to keep your neck warm while looking polished and sophisticated.

Depending on your face shape, you might prefer a half-turtleneck or mock neck to frame your face. On the flip side, some people look gorgeous with lots of fabric draped around the neck. Try a few to find yours. Layering a turtleneck under a sweater or coat is also a beautiful way to add warmth and polish.

4. Cardigans

Cardigans button up the front, which makes them wonderfully versatile for layering. Style them over dresses or tees, or wear your cardigan buttoned as a top on its own.

Cardigans are mostly defined by length: cropped, hip-length, knee-length, maxi and everything in between. Try a few lengths to see what works best with your wardrobe.

Four comfiest fabrics for winter sweaters

Your sweater's fabric can make or break the whole outfit. If it's itchy, uncomfortable or too heavy, you probably won't wear it very often. So let's explore some of the comfiest, most eco-friendly materials for winter sweaters.

1. Wool

Wool sweaters are known for their warmth and insulation. They're soft, naturally breathable and a more sustainable option than synthetics. Wool is also a favorite for outerwear, like the timeless camel coat.

Merino wool is an excellent choice because it's super soft and not itchy. Shopping online can be tricky when you can't feel the fabric, but merino is a reliable way to know you're getting something comfy and durable.

2. Cashmere

Cashmere is synonymous with luxury, warmth and elegance. Cashmere sweaters are lightweight yet durable, and they get softer with wear and washing.

Quality cashmere is an investment, but it's worth it. I've had some of my favorite cashmere sweaters and cardigans for nearly a decade, thanks to a little care and a whole lot of love. Buying it preloved is the smartest way to get the good stuff for less.

3. Cotton

Cotton is the most versatile and common fabric out there, perfect for layering or milder winter days. It's breathable, easy to care for and comfortable from morning to night.

Organic or recycled cotton is your best bet for eco-friendly wear. Check out these seven eco clothing materials to learn the difference between new, recycled, organic and sustainable textiles.

4. Synthetic blends

Many modern sweaters use synthetic blends like acrylic, polyester and nylon. These blends add warmth and durability and are easy to care for.

However, synthetic blends are generally not sustainable: they're made through resource-heavy processes and shed microplastics. If you love a synthetic sweater, buy it on consignment. You get all the benefits while keeping an existing piece in use.

Sweater trends worth knowing this winter

The classics above never go out of style, but a few sweater trends are worth playing with right now. Many of them you can try with pieces you already own! For the full rundown of the season, see our winter 2026–27 fashion trends.

Top button closed

Buttoning only the top button of a cardigan is a simple '90s trick that turns an ordinary cardigan into a statement and lets a peek of blouse show through. Pair it with high-waisted pants or a fitted skirt to balance the open shape below.

Big, dramatic necklines

Slouchy, oversized necklines and funnel necks are the dramatic cousins of the turtleneck: roomy and cozy, yet polished. Keep the rest of the outfit simple and let the neckline lead.

Knits with built-in scarves

Sweaters and jackets with an attached scarf give you warmth without extra bulk. In cashmere or mohair, they pair beautifully with tailored trousers.

Preppy golf sweaters

Collared V-neck knits and argyle fit right into quiet luxury. Layer one over a crisp shirt with tailored pants and loafers for an easy old-money look.

Playful appliqué knits

Embroidered bows, fruit or animals add personality. Let the sweater be the star and keep everything else simple.

The turtleneck tee

A lightweight turtleneck T-shirt gives you the warmth of a high neck without the bulk, so it layers easily under blazers and cardigans.

Long cardigans

The long cardigan is back. Wear it open over jeans or a dress, or button it up as a sweater dress with tall boots.

Leopard knits

Leopard has officially become a neutral. A leopard sweater mixes beautifully with burgundy, deep green or camel. Here are our secrets to rocking animal prints.

Rich, warm colors

Burgundy is still the sweater color to own, joined by plum, bottle green and chocolate brown. Not sure which suits you? Try our DIY color analysis.

How to style sweaters for a chic winter look

With the right accessories and a little creativity, you can be both cozy and chic all season. Here are my favorite styling tips.

1. Layer with a scarf

A well-chosen scarf can complement your sweater's color, texture and style for a beautifully put-together outfit. Browse our designer scarves.

2. Mix and match textures

Combine fabrics for an eye-catching look: a cashmere turtleneck under a chunky wool sweater, or a quilted vest over a crewneck. Here's more on mixing textures.

3. Oversized sweaters and leggings

One of my favorite winter outfit formulas is an oversized sweater or sweater dress with leggings or tights. The slim leg balances the volume up top and lengthens your silhouette.

4. Belt your sweater

Cinch an oversized sweater or sweater dress at the waist with a belt for a flattering hourglass shape.

5. Layer with a long coat

Throw a long overcoat or trench over your knit for a timeless look that's snug and chic. Shop our coats and jackets.

6. Try a monochrome look

Pair your sweater with bottoms in the same color family for an elegant, harmonious outfit.

Winter sweater FAQ

What is the warmest sweater fabric?

Wool and cashmere are the warmest natural fibers for their weight. Merino is the best pick if regular wool feels itchy.

Wash them inside out on a gentle cycle (or by hand), lay them flat to dry, fold rather than hang, and remove pills with a fabric comb. More tips in our hacks to make your clothes last longer.
