Cozy sweater dresses were all over our Instagram feeds back in fall 2020, and now they’re back to rule our wardrobes once again. Yes, you can continue to rock your summer knit versions so long as the weather is warm, but after Labor Day we can’t help but find ourselves drawn to cozier silhouettes and more autumnal materials, like cashmere and wool.

Beyond being incredibly comfy, knit dresses are also incredibly versatile and look equally stylish with sneakers, heels and boots. You can dress them up for date night with some standout heeled booties and bold statement earrings, or go casual for a weekend at home with Keds and a silk scarf to tie around your ponytail.

Below, 20 of the most flattering, most comfortable sweater dresses to toss on this fall—and keep wearing all the way through to the end of the year.

12. Jonathan Simkhai Skyla Loungewear Knit Wrap Dress

Imagine a luxe cashmere robe you can actually wear outside the house without attracting odd looks from the neighbors.

staud fall sweater dress
Saks Fifth Avenue

13. Staud Shoko Colorblock Sweater Dress

For fall we suggest wearing this fun two-tone knit as a dress with knee-high boots or as a cardigan over a slip dress. For winter, rock it as a true cardigan layered over turtlenecks and jeans. And for spring you can button it up to wear as a dress and keep your accessories on the minimalist side in shades of white or delicate metallics. A true triple threat.

Available in sizes XS to XL

Another fun multi-season option, this dress works particularly well for those weird days between summer and fall when the weather isn’t entirely sure what it’s doing.
