Long cardigan outfits: with a T-shirt, a shirt and trousers

Stacy EditionOctober 2, 2026

How do you wear a long, open-front cardigan?

In long cardigan outfits, what counts is what you wear underneath. An open-front cardigan is left open and worn as an outer layer over something simple, such as a T-shirt, a shirt or a dress. The long vertical line running down either side belongs to the cardigan; what shows in the middle belongs to the piece underneath. Keep that piece simple and the cardigan stays in the foreground.

Worn on the shoulders with the front open, the cardigan keeps its vertical line; slipped slightly off them, it brings the wide sleeves to the fore.

The examples come from the Cashmere capsule. Its long, open-front knit cardigans come in three colours (white, beige and black) and are made of 100% viscose, soft and light. They are one size and adapt to different body types. The model in the photos is 170 cm tall; in some shots she is wearing heels.

A long cardigan with a T-shirt, a shirt and trousers

With a T-shirt

A solid-colour T-shirt in a simple cut balances a wide-sleeved cardigan well. Save striped or patterned ones for another outfit; the knit texture of the cardigan draws enough attention on its own. Because the sleeves are wide, a short-sleeved or sleeveless top can be a good choice; if you wear long sleeves, choose a slim-sleeved one. The neckline changes the look too: a low neckline continues the vertical line of the cardigan's open front, while a high neckline gives a neater line at the neck.

With a shirt

A shirt's collar can show in the open front of the cardigan, so a plain one in a single colour, such as white or light blue, will do. Leave a few buttons undone: collar and cardigan together give a more relaxed feel.

With trousers and jeans

If you are wearing trousers or jeans with it, choose a pair in a single colour with no detailing. The cardigan already makes a statement with its length and wide sleeves; with a plain lower half, the emphasis stays on the cardigan. To keep all the volume in the cardigan, try a slim-leg pair; to continue its fluid line, try wide-leg trousers.

Proportion and silhouette in a long cardigan

A long cardigan draws a strong vertical line on its own; the rest is down to what you wear with it. Tucking in just the front of the T-shirt or shirt defines the waist in the cardigan's open front and leaves the rest of the top loose. Leaving it fully untucked works too, and gives a longer, more relaxed silhouette with the cardigan. Trousers that reach the ankle, or are turned up slightly, show off your shoes and complete the line. As for accessories, a fine, long necklace fills the open front.

Weekend, workday and evening

For the weekend, a T-shirt, jeans and flat shoes are all you need; loafers or white trainers keep things understated next to the cardigan. On a workday, choose a plain shirt and smart trousers; the cardigan becomes an outer layer that takes the place of a jacket. For the evening, wear the black cardigan with slim heels; the heel lengthens the silhouette further. There is a simple rule for bags, too: a shoulder bag can slide the cardigan off your shoulder, while a hand-held bag or a cross-body bag suits this outfit better.

A long cardigan with a dress

You can also wear the cardigan over a dress; if the dress is the same colour as the cardigan, the silhouette looks long and unbroken from top to bottom. If you would like to buy the two together, a dress and cardigan set in the same colour is 10% off in the Cashmere capsule.

Outfit ideas by colour

All three colours of the long cardigan are neutral; what sets them apart is what you pair them with. Pick a piece in the same tone as the cardigan and the look is calmer; pick a contrasting tone and the cardigan catches the eye. If dark tones dominate your wardrobe, start with the white cardigan; if light tones do, start with the black one. Beige is the middle ground if you are undecided.

White cardigan outfits

White gives an outfit a fresh, clean feel. Wear the Cashmere White Cardigan with a dark T-shirt and dark jeans and it becomes the only light-coloured piece in the outfit; the contrast takes care of itself. For a softer transition, choose an ecru T-shirt.

Beige cardigan outfits

The Cashmere Beige Cardigan pairs easily with other neutral tones. You can stay in the same colour family with shades of brown and cream, or add contrast with dark jeans. A white shirt and light-coloured trousers keep the whole look bright.

Black cardigan outfits

Wear the Cashmere Black Cardigan with a white T-shirt or shirt and the contrast is crisp; a light grey T-shirt softens it slightly. Worn with all black, the cardigan stays a quiet outer layer.
