A cardigan can be the top or the layer: buttoned with trousers, open over a tee, under a coat, or standing in for a blazer. Five outfits below, half of each.
A cardigan buttoned as a top puts its neckline on show, and a V-neck and a crew neck flatter different builds. Wdrobe, an app we make, suggests necklines that suit your shape from a single full-body photo.
Buttons, length and what goes underneath
Pay attention to neckline, button placement, knit thickness, and whether it works open and closed. Try it with the shirt and shoes you have; both decide whether it reads as a top or a layer. Button it and raise your arms: if the band gapes or pulls between the buttons, the cardigan is a size too small to wear closed.
A practical palette for a cardigan is denim, cream, black, camel, and soft gray. Two will do. A cardigan is usually the color you notice, so let the rest stay quiet. Picking the cardigan's color up again in a shoe keeps it from looking like the only thought in the outfit.
5 ways to style a cardigan
1. Buttoned cardigan + straight jeans + loafers
The cardigan as a top. A fine-knit one that ends at the hip, or just over the waistband of high-rise jeans, looks neatest buttoned all the way; with a V-neck, leave the top button open. Straight jeans that show the ankle and brown or black loafers keep the outfit light. If the knit is sheer, a thin camisole underneath in your skin tone is enough.
2. Open cardigan + fitted tee + wide pants
The cardigan as the layer. Left open, a hip-length or longer cardigan makes two vertical lines down the front, which balances the volume of wide trousers. Keep the tee fitted and tucked in so the waist still shows. A white or striped tee and white trainers make it casual; a silk camisole and pointed flats make it right for the office.
A cardigan tips an outfit towards cosy very easily. Whether it does depends on the weight and what is under it. See how yours reads in a full outfit.
3. Cardigan over a slip dress + ballet flats
Soft knit against shiny satin is the point of this one. A cropped cardigan that stops at the natural waist keeps the line of the slip dress; a long one hides it. Do up only the middle button or two, so the dress shows above and below. In autumn, add sheer black tights and swap the flats for ankle boots.
4. Cardigan + midi skirt + knee boots
A smart autumn outfit for the office or the weekend. Tuck a fitted cardigan into a pleated or satin midi skirt, or wear a cropped one over it, so the waist shows. The boots should meet the hem or disappear under it, because a strip of bare leg between them breaks the line. A chunky cardigan needs a smooth skirt; a fine one can take corduroy or a knitted skirt.
5. Cardigan under a blazer + tailored pants
The cold-office version. A thin merino or cashmere cardigan fits under a blazer without bulk at the shoulders; a chunky one will not. Wear it buttoned like a jumper, in a colour close to the blazer or the trousers, so the layers read as one outfit. Pull the cuffs down before the blazer goes on, and check the knit is not bunching at the underarm once the blazer is on.
Buttoned, open, or on its own
A fine knit works alone in spring, a heavier one replaces a jacket in autumn, and either goes under a coat in winter. Buttoned up with tailored trousers, a cardigan reads as a knitted blazer. Open over a tee it is the least formal layer you own.
A gray cardigan with black trousers reads office; the same knit over denim does not.

Frequently asked questions
What do you wear under a cardigan?
Nothing, if you button it as a top, or a thin camisole if the knit is sheer. Worn open, it goes over a fitted tee, a thin shirt or a silk camisole. Keep the layer underneath smooth and close-fitting so the knit hangs straight.
Can a cardigan replace a blazer?
For smart-casual settings yes, particularly a fitted one in a fine knit. For formal environments a blazer's structure does something a cardigan cannot.
How do you stop a cardigan looking frumpy?
Choose a fine knit, check the shoulder seam sits on your shoulder, and look at where the hem lands. A hem at the widest point of your hips, or one long enough to hide the waist, is usually the cause. Shortening the body or moving the buttons is a small alteration.
What shoes go with a cardigan?
Loafers or ballet flats with a buttoned cardigan and jeans or tailoring, white trainers with an open one over a tee, and knee or ankle boots with a skirt or dress in autumn.
For heavier knitwear, chunky knit sweater outfits covers the jumper version, and spring layering outfits shows where a fine cardigan sits under a jacket. A cardigan is a layer and a top at once, which is why it earns its hanger; to find the other clothes that do double duty, try shopping your own closet for outfits.
A cardigan changes completely depending on whether it is belted, buttoned or open, and most people default to one of the three. Build the other versions with your own clothes and save the ones worth repeating.
