Buy casual clothing: how to choose comfortable basics that suit you

Casual clothing in the UK has to stand up to daily wear and tear: cycling to work, doing the supermarket shop, going for a walk or relaxing at home. Even so, an online purchase can sometimes disappoint. A T-shirt might fit differently than expected, a jumper could be too warm, and a jacket that looks great in the product photo might turn out to be far from practical.

The main pitfalls when it comes to casual clothing are usually:

  • Relying solely on the size letter: a small or medium varies from brand to brand, model to model and fit to fit.
  • Confusing marketing claims with measurable features: terms like “breathable”, “durable” or “sporty” don’t tell you much without the fabric, cut and care instructions.
  • Ignoring care requirements: a garment that can only be washed on a delicate cycle takes more time than an everyday basic that can simply go in the machine.

With the right checks in place, you can compare women’s clothing, men’s clothing, sportswear and basics such as T-shirts, jumpers, hoodies and cardigans much more effectively.

What to look for in casual clothing

1. Check the fabric and composition

The fibres largely determine how a garment feels and how it can be worn.

  • Cotton generally feels soft and works well for T-shirts, blouses and everyday tops.
  • Polyester is lightweight and is often used in sportswear and jackets.
  • Recycled polyester tells you something about the raw material, but not automatically about the fit, durability or comfort.
  • Wool and elastane can add extra warmth or stretch in a blend.

Always check the exact percentage. A T-shirt made from 100% cotton is a different choice from a model with a blended composition. For the Nike Park 20 Tee, the product details state 57% cotton and 43% polyester. The product description also mentions Nike Dri-FIT; treat that as a claim from the brand and check whether that feature suits your needs.

2. Compare the fit, chest size and room for movement

A regular fit usually sits somewhere between snug and roomy. A slim fit is closer to the body, while a relaxed or oversized model offers more space. So don’t just look at “S”, “M” or “L”, but also at:

  • chest or bust width;
  • garment length;
  • shoulder width and sleeve length;
  • room at the waist;
  • the layer you plan to wear underneath.

For example: a sweatshirt you want to wear over a T-shirt should be roomier than a blouse you’ll wear under a blazer. The adidas Trefoil Essentials Crew Sweatshirt in size S lists a chest width of 48 cm and a regular fit. The North Face version, on the other hand, has a relaxed fit, which the product information says is slightly looser.

3. Look at care instructions and intended use

A low price is less appealing if a garment quickly loses its shape or needs a lot of attention. So check the care label and see whether the item suits your routine.

Pay attention to:

  • maximum washing temperature;
  • whether it can go in the tumble dryer;
  • ironing instructions;
  • colour washing and washing inside out;
  • sensitivity of prints and embroidered logos.

A dark jumper with a print or embroidery will generally stay looking better if you follow the instructions. The adidas Trefoil Essentials Crew Sweatshirt advises, among other things, washing inside out, washing dark colours separately and not ironing directly over the motif.

Frequently asked questions about casual clothing

Which casual clothing is suitable for everyday wear?

Choose basics that are easy to mix and match and for which the fabric, fit and care instructions are clear. A cotton T-shirt, regular-fit jumper, cardigan or simple blouse often works well as a foundation. For changeable weather, you can add a cardigan or lightweight jacket.

How do I determine the right clothing size online?

Measure a garment that fits you well and compare the chest width, length and fit with the product information. Also pay attention to the difference between slim fit, regular fit and relaxed fit. For women’s clothing, the waist and hips can be more important than just the bust measurement; for men’s clothing, chest width and shoulder room often play a bigger role.

How can I keep casual clothing looking good for longer?

Follow the care label, wash dark colours separately and use a mild detergent when recommended. Air-dry T-shirts and jumpers if the product instructions advise against using the tumble dryer. Don’t iron directly over prints and embroidered logos. This will limit unnecessary wear and tear and help the fit last longer.
