It's officially knitwear season, and even though our collection has expanded quite a bit in the last few years (hello, cardigan sets, knit boleros, and knit skirt sets, to mention a few), there's one item, in particular, that's a step above the rest. We're talking about knit dresses, specifically ribbed-knit dresses. Maybe it's because they add an effortless vibe to all our fall and winter outfits; maybe it's because they're supremely comfortable, easy to put on, and happen to look expensive regardless of price; or maybe it's because we haven’t found a style yet that we don’t like. Whatever the reason, they're the dominating dress trend this season, and we're so here for it.

If you’ve been eyeing the trend but haven’t found the outfit inspiration you needed, then look no further than the best ribbed-knit dresses below. We’ve charted the trend's path from the fall 2021 runways to our Instagram feeds and now to our carts. So scroll down to peruse a selection from some of your favorite retailers, and glean some styling inspiration from your favorite street style stars who’ve worn theirs with everything from heeled mules to chunky boots. In other words, there’s enough inspiration ahead for the rest of winter and even those transitional weeks to come.

On the fall runways:

Gabriela Hearst sent ankle-grazing ribbed dresses down its runway layered over trousers, solidifying them as the ultimate fall layering item.

At Bevza, long silhouettes were punctuated by cool, skin-exposing cutouts that are simple but striking.

Fendi's take involved a classic beige hue and off-the-shoulder neckline that's both of the moment and timeless.

While plenty of designers showed ribbed dresses on the more conservative (read: wearable) end of the spectrum, the ones at Dion Lee were decidedly risqué with plenty of eye-catching cutouts.

Ganni styled the ribbed dresses in its fall collection with another favorite fall trend, chunky lug-sole boots, and plenty of fashion people have since followed suit.

Style notes: We loved the idea of a ribbed dress with easy-to-wear cutouts so much that we went ahead and made our very own, and TBH, we're not surprised by how popular it became.

Style notes: These easy dresses pretty much style themselves, so keep it simple with go-to accessories like gold hoops and black sunglasses.

Style notes: We're seeing more and more of these simple silhouettes that feature an out-of-the-box neckline, and we're obsessed.

Style notes: While boots are an obvious choice, you can also wear a knit dress more casually with retro sneakers.

Style notes: To really make your overall silhouette pop, try belting your dress with a chain-link belt.

Style notes: Neutral tones like tan, camel, and beige are really where these ribbed numbers shine.

Style notes: In a pinch? Classic mules and a belt make for a fail-safe fall-and-winter outfit.
