7 No-Frump Ways to Wear Chunky Knit Sweaters
Chunky knit sweaters are roomy, cozy, and incredibly comforting—especially on those chilly days when you just want to wrap yourself in something warm and snuggly. But they’re not without their challenges. If you’re petite, you have to be careful they don’t swallow you up. And if you’re already a little rounder or softer (like many of us are after 40), all that bulk and texture can easily add visual weight.
So how do you wear a chunky sweater without looking frumpy at 40, 50, 60, and beyond? Here are 7 smart, stylish ways to make a chunky knit work—no matter your age or body shape.
1. Double-Check the Fit
Chunky knits are meant to be relaxed—but there’s a fine line between oversized and just plain overwhelming. Size up too much, and you risk looking shapeless. Size down too far, and it can cling in all the wrong places.
Look for a sweater that fits well in the shoulders and has enough structure to skim (not swamp) your shape. Scrunch the sleeves, half-tuck the front, or even belt it to give it a little more polish. And if it’s a belted cardigan, make sure the belt sits at your natural waist—not your hips.
2. Wear Long Over Skinny
This is the golden rule when wearing a chunky oversized knit: balance the volume. A slouchy turtleneck or roomy pullover looks best with skinny jeans, leggings, or slim-cut trousers. This wide-on-top, narrow-on-bottom formula creates a flattering silhouette that feels modern and intentional.
Wearing wide-leg pants or a long skirt with a chunky sweater can make your whole frame look boxy—unless you’re careful with tucking and proportions.
3. Choose a Cropped Chunky Knit
If you like the chunky sweater trend but don’t love the bulk, try a cropped version. These look especially chic with high-waisted pants or jeans, and you can wear them with slim, straight, or even wide-leg bottoms. You’ll still get that cozy texture without the overwhelm.
4. Layer Lightly
When layering under a chunky knit, keep it light and simple. A silky button-down or crisp white shirt looks great under a cropped cable knit—especially if you let the shirt tails peek out for a preppy vibe. Camisoles, lightweight tees, and fine-knit tops are also great options under cardigans.
Tip: Leave cardigans open, or button just a few and add a belt for shape.
5. Petites—Skip the Long & Oversized
If you’re petite, chunky knits can be tricky. The key is to go for smaller-scale textures and slightly more fitted styles. Cropped knits, medium-weight yarns, and vertical details will flatter your frame without drowning you in fabric.
6. Look for Vertical Details
Slim your silhouette with chunky knits that have vertical elements like a row of buttons, a zipper, or ribbing that runs lengthwise. Even diagonal lines or asymmetrical hems can help visually elongate your frame and break up the bulk.
7. Choose Modern Colors and Styles
We all love a cozy grandpa sweater—but some styles can veer into frumpy territory fast. Think twice before reaching for patchwork knits or old-school patterns that look too crafty. Instead, opt for color-blocked designs, ombré, or simple solids with texture. (Although I did find a modern-looking white patchwork one I love—so never say never!)

I’m not a fan of chunky knits for any age – they look frumpy on just about everyone. Your tips are fantastic, though!
Hi Deb, Thanks for your honesty on this. You make a good point. We have suggested in the past to beware of chunky knits since they can add unwanted bulk to our bodies. (and who wants that?)… so, when buying sweaters, we love to find those on the thinner side. However, some of us live in frigid climates, so we might have to bulk it up at some point!
If that’s what women over 40 are wearing, I’m going to start shopping in the Jr’s department…were over 40, not frumpy!!!!!
How do you feel about the cascading sweaters on a concise slight apple shape? I’m having difficulty trying to visualize whether this would be elongating and slimming or if it would simply call attention to my tummy. By the way, I’m an advanced-level seamstress who would be making the sweater, so I can adjust the amount of fullness, length, etc., and come up with a perfect fit.
What do you think of leggings on women over 40?
I bought a pair, then returned them the next day after reading a great article in More Magazine about how women over 40 should never wear them. (My husband agreed with the theme….) ?
Fall fashion is excellent and my favorite time to buy clothes! Yeah! Fall is coming.
