Choosing knitted jumpers and cardigans: practical tips for comfort, fit and layering

Buying a new jumper or cardigan seems simple until the fit is disappointing, the fabric turns out to be too warm or the garment loses its shape after a few washes. With knitted jumpers and cardigans, the material, size and care instructions are generally more important than attention-grabbing marketing copy.

Look out for these common pitfalls:

  • A soft touch does not tell you everything: a fabric may feel soft when it arrives, but its composition partly determines how the garment behaves when worn and washed.
  • “Suitable for every season” is not a fixed benchmark: medium-weight knitwear is useful for layering, but is not automatically suitable for a cold winter’s day or a warm room.
  • The size on the label is not enough: an M or L can fit differently depending on the model. Check the fit, length and room around the shoulders and arms.
  • Care is often underestimated: washing at too high a temperature, bleaching or tumble-drying can affect the garment’s shape and appearance.

The key points to consider before ordering

1. Check the material composition

A cotton blend combines different fibres. According to the product description, the blue US Polo Assn jumper consists of 70% cotton and 30% polyamide. Cotton feels familiar and works well for everyday wear. Polyamide can contribute to lightweight, fluid-fitting knitwear, but the feel when worn varies from person to person.

A polyamide cardigan, such as the Levi’s Black Betty cardigan, is made from 100% polyamide, according to the product information. This is a different choice from a blue cotton jumper: the cardigan has a lightweight drape and is designed to be worn easily over a shirt, blouse or dress.

As well as the percentage, look at the thickness of the knit. A medium-weight knit is often practical for indoors, transitional weather and layering. For extra warmth, it is not just the type of fibre that matters, but also the density and construction of the knit.

2. Choose the fit based on how you will wear it

A jumper with a round neck and long sleeves is easy to wear over a T-shirt or under a coat. Ribbed cuffs and an elasticated hem can help keep the sleeves and lower edge in place. The product description for the US Polo Assn models specifically mentions these details.

A cardigan offers greater flexibility. You can wear a women’s cardigan open, fasten it when the temperature drops or combine it with several layers. Pay particular attention to the shoulder width and sleeve length. If you like wearing a blouse under your cardigan, you may need more room to move than someone who wears it directly over a top.

Do not use size M or size L as your only deciding factor. Also check:

  • whether you want a fitted or looser fit;
  • how many layers you will wear underneath;
  • whether the hem falls on the hips or above them;
  • whether the sleeves are long enough when sitting and cycling;
  • whether the model is listed as women’s or unisex clothing on the product page.

3. Check the care instructions before buying

The US Polo Assn jumper states machine wash up to a maximum of 30°C, do not bleach, do not tumble-dry and iron at a low temperature. The Levi’s Black Betty cardigan can also be washed at a maximum of 30°C; tumble-drying on a low setting and ironing at a maximum of 110°C are permitted according to the product information.

Always follow the care label on the item you receive. Ideally, wash knitted clothing with similar colours, avoid unnecessarily high temperatures and check whether the garment needs to be dried flat. This helps reduce the risk of distortion, particularly with soft knitwear.

How to style knitted clothing in the Netherlands

For changeable weather, layering is often more practical than wearing one very thick garment. Wear a blue cotton jumper over a T-shirt and add a coat when it is windy. A black women’s cardigan is useful for the office, working from home or an evening when the temperature drops.

Coordinate colours with your existing wardrobe:

  • Blue or navy: works well with denim, beige, grey and white.
  • Black: goes with almost all neutral shades and can tone down a more eye-catching blouse.
  • Round neck: suitable for a simple, casual look.
  • Cardigan: useful when you want to put the garment on and take it off throughout the day.

Frequently asked questions

How long does a knitted jumper or cardigan last?

Its lifespan depends on the fibres, knit, frequency of wear and care. Wash according to the label, avoid unnecessarily hot washes and do not use bleach unless permitted. Do not leave knitwear hanging on a hanger for extended periods if this could cause the material to stretch.

Is cotton or polyamide better suited to everyday wear?

That depends on your preference and how you intend to use it. Many wearers find cotton familiar and the US Polo Assn models contain 70% cotton. According to the product description, polyamide can have a lightweight, fluid drape, as with the Levi’s Black Betty cardigan. Always compare the full composition and care instructions.

Which size should I choose: M or L?

Choose based on your body measurements, the size guide and how much room you want. Size M is often suitable when you are looking for a more fitted layer; size L generally offers more room for a shirt or blouse underneath. Also check the sleeve and back length, as these vary between models.
