A long cardigan is meant to hit somewhere between mid-thigh and the knee, long enough to work as a layer over leggings or a dress rather than just a cropped topper. These are the open-front, belted and duster lengths I would actually wear, from soft lounge knits to wool that holds a line like a coat.

A long cardigan is meant to hit somewhere between mid-thigh and the knee, long enough to work as a layer over leggings or a dress rather than just a cropped topper. The good ones hold their shape through the shoulders and drape rather than cling at the hip, which is where a poorly made knit usually falls apart first. Fabric weight decides everything else: too thin and it looks like a robe, too heavy and it stops moving when you walk.
The first twelve are the easy ones, the open-front shapes I would actually throw on over a T-shirt. T Tahari, Majestic Filatures and Seasalt Cornwall all fall loose from the shoulder, and Majestic's cotton blend is the thinnest, so it slides under a coat without bunching at the arm. Chinti & Parker's wool-cashmere is the one in this row I would keep for years, light rather than bulky. THE GREAT.'s Stetson collaboration and Free People's patchwork Enid bring a little pattern. The C by Bloomingdale's cashmere duster and JLUXLABEL's Soft Embrace are the longest layers in the group, so I would try them over leggings or a slim knit dress and keep everything underneath plain. House of Dagmar's long wool cardigan and Citizens of Humanity's Kari are the cleanest lines in the group, and Vince's draped sweater coat and Splendid's Aria open jacket add a shawl collar when you want something that sits like a light coat.

Wool with some structure
Achille Maramotti started Max Mara in Reggio Emilia in 1951, and the house built its name on coats. You can feel that in both Max Mara cardigans here: the Long Wool Yarn and the Long Jacquard are dense enough to hold a straight line to the knee, closer to a soft coat than a sweater. Arch4's Bond Street is cable-knit cashmere, heavier through the body, and Theory's open-back rib is the sharpest shape of the set.
Karen Kane's Long Cardigan and Halogen's Open Front Longline are the everyday versions, with patch pockets and an easy drape. Petal & Pup's Lenore adds notched lapels, so it reads almost like a blazer, and Velvet by Graham & Spencer's Leona08 has a shawl collar that sits like a cardigan coat. My test for all of them is the same: reach forward and see where the sleeve lands before you judge the hem. A long body with a short sleeve throws off the whole proportion.
What I would skip: a heavy cable knit under a fitted wool coat. Pick one bulky layer, not two.

Dusters, wraps and the dramatic end
Ottavio and Rosita Missoni founded their house in Gallarate in 1953 and made knitwear a high-fashion medium, so the Missoni Long Cardigan is the loudest piece here and the one I would wear as the whole outfit. Sablyn's Toma is a slouchy cashmere duster and La Vie Style House goes to maxi length, both made for movement over a dress.
Barefoot Dreams' CozyChic Ultra Lite is the soft, lounge-weight option, and Max Mara's jersey wrap belts at the waist when you want some shape. Petal & Pup's Audrina ties at the front too, and so do Max Mara Leisure's hooded Nava, oyun's mustard Erte and HOUSE OF CB's Madison further down. Trina Turk's chartreuse Carducci and Pretty Lavish's Dora go all the way to the ankle, which is the length I reach for over a slip dress. matty m.'s Colfax is the lightest rib in the grid, the one I would pack for a cold plane.
The rest of the grid is the long-knit bench I scrolled for ages. By Malene Birger's Serafina is the long, lean one, Vince and Eileen Fisher do the quiet shawl-collar wool, and L'AGENCE's Orielle and Soia & Kyo's Zola sit somewhere between a cardigan and a coat. Yumi's maxi knits and Pendleton's cotton duster are the easy weekend layers, while Bimba y Lola and Dressed in Lala bring the fringe if you want the cardigan to be the outfit.
What I would skip: belting a duster over a full skirt. Save the belt for slim trousers or a column dress.

The fit check I make
I check sleeve length before I decide whether the body length works. I reach forward, sit down, and look at where the shoulders settle. That small test tells me whether a long cardigan will layer well or only look good standing still.
Wool holds its shape at the shoulder far longer than acrylic does, which matters more on a long cardigan than on a short one, because all that length hangs from two seams. If you want to keep browsing, I also put together Cardigan Or Jumper For Layering and The Cardigan as a Top.
