Choosing jumpers and sweatshirts: how to find a comfortable style that suits you

Choosing a new jumper may seem simple, but online photos don’t tell the whole story. A knitted jumper can look soft and thick on screen, yet feel thin in real life. A neckline that’s too tight, unclear sizing or difficult care instructions can also mean you rarely wear it.

Use these tips to compare jumpers and sweatshirts in a practical way. Look beyond colour and brand to consider fit, fabric, when you’ll wear it and how to care for it.

Common pitfalls when buying a jumper

1. Marketing language means little without a fabric label

Words such as “warm”, “soft” and “premium” are only useful when the fibre content is listed too. A cotton jumper often feels comfortable and is suitable for everyday wear, but it won’t necessarily provide the same insulation as a wool jumper. For blends containing wool, cashmere, silk or synthetic fibres, the percentages are particularly important.

So, check:

• the exact fabric composition;
• whether “cashmere” is actually listed in the composition;
• whether the garment is lined, fleece-backed or simply chunky-knit;
• the washing and drying instructions.

2. A flattering fit can be impractical in everyday wear

A regular-fit jumper is usually roomier than a slim-fit style and works well for layering. A long women’s jumper can offer extra coverage, but may bunch up under a coat. A men’s jumper with a high neck gives your neck more protection, but might feel less comfortable if you prefer to wear a shirt or T-shirt underneath.

Check the recommended body measurements, not just S, M, L or XXL. Sizing varies between brands and sometimes between products, too. For international offers, also check whether the size guide uses European sizing.

3. Care is often only considered after purchase

A wool jumper, cashmere jumper or fine-knit style may need more care than a cotton sweatshirt. Not every garment is suitable for tumble drying. Some should be dried flat to help prevent stretching. A low washing temperature won’t always prevent shrinkage: the fabric and recommended drying method matter too.

The key specifications to compare

Fabric: choose based on how you’ll wear it, not just how it feels

• Cotton: suitable for everyday wear, layering and changeable temperatures. JACK&JONES lists the model mentioned here as 100% organic cotton.
• Wool and merino: often chosen for colder days. Check the composition and washing instructions, as warmth and feel vary depending on the knit.
• Cashmere blend: can feel soft, but usually needs more careful care. A higher cashmere percentage doesn’t automatically mean the fit or durability will suit the way you plan to wear it.
• Viscose and polyamide: can create a knit with a soft drape. The ONLY MILA LIFE jumper combines these fibres and has a longer cut with a crew neck.
• Fleece and sweatshirt fabric: practical for relaxed outfits, working from home or outdoor activities. A zipped hoodie is easy to wear open and works well for layering.

Neckline and construction

A crew-neck jumper is versatile and easy to wear with a T-shirt or shirt. A roll-neck jumper or high neck can offer extra protection from cold air. Ribbed cuffs and hems help keep a jumper in place, but make sure they aren’t too tight.

For a sweatshirt or hoodie, the zip, hood and cuffs are worth checking too. A full-length front zip makes it easier to adjust your temperature than a closed style.

Fit, size and length

Look at:

1. Shoulder seam: for a regular fit, it shouldn’t sit far beyond your shoulder.
2. Sleeve length: especially important for a men’s or women’s jumper worn under a coat.
3. Back length: worth checking for longer styles and when layering.
4. Room around the chest and waist: enough freedom of movement helps prevent the knit from pulling.
5. Size guide: compare the listed measurements with a jumper you already find comfortable.

A black jumper is easy to pair with jeans, chinos or a skirt. Check the care instructions to help minimise fading and loss of shape.

Care tips to help your jumper last longer

Always follow the label in the garment. General tips:

• Turn knitted garments inside out and wash them with similar colours.
• For wool and cashmere, only use a suitable programme if the label allows it.
• Avoid tumble drying if there’s a risk of shrinkage or misshaping.
• Dry heavy jumpers flat rather than hanging them up while wet.
• Iron at a low temperature and don’t use bleach unless the care instructions allow it.

Frequently asked questions about jumpers and sweatshirts

What’s the difference between a jumper and a sweatshirt?

A jumper is usually knitted and may be made from cotton, wool or a blend of fibres. A sweatshirt is often made from sweatshirt fabric or fleece and has a sportier look. The distinction isn’t always clear-cut, so check the fabric description and construction.

How do I choose the right size when buying a jumper online?

Compare the size guide with a garment you already own. Measure the chest, shoulders and length. If you plan to layer, leave enough room around the shoulders and arms. Check whether the style is slim fit, regular fit or relaxed fit, too.

How can I stop a knitted jumper from losing its shape?

Follow the care label, avoid high temperatures and dry the garment flat if instructed. Don’t leave a heavy, wet knitted jumper hanging for long: its weight can affect the shoulders and length.
