How to choose sportswear and casual clothing without making a bad purchase

Buying comfortable sportswear and casual clothing seems straightforward – until a pair of trousers loses its shape after a few washes, or a T-shirt turns out to be less suitable for training than you expected. The logo doesn’t tell you everything. For football, fitness, everyday wear and relaxing, the material, fit and care instructions matter just as much.

Joybuy Product Recommendation Officer filters the key product information and turns it into practical choices. That way, you can compare sportswear based on verifiable features, rather than marketing claims alone.

Common pitfalls when choosing sportswear

1. Mistaking a sporty look for technical performance

A T-shirt with a prominent sports brand logo isn’t automatically suitable for intense training. Check whether the garment is designed for sport or mainly for everyday wear. A cotton adidas T-shirt or The North Face men’s T-shirt can be comfortable for leisure, but its properties differ from those of a polyester training shirt.

The product description for the Nike Dri-FIT Park 20 Tee mentions moisture management, lightweight fabric and a regular fit. However, the available product information lists different material compositions: the full description says 100% polyester, while the product specifications state 57% cotton and 43% polyester. Always check the current product specifications and care label before ordering.

2. Choosing the wrong size because of international size charts

An M isn’t the same across every brand. Some product pages show EU, UK, US or JP sizes side by side. So don’t just look at the letter size – check the chest, waist and hip measurements in centimetres too.

For example, the adidas Trefoil Essentials Pants lists a waist range. For XL, it’s 91–96 cm, while other sizes have smaller ranges. For size M, the Under Armour joggers list a waist measurement of 79–86 cm and an inside leg of 76 cm. These figures are more useful than the general description ‘true to size’.

3. Ignoring care instructions

Fleece, cotton and polyester react differently to washing and drying. According to the product information, an adidas sweatshirt made from 70% cotton and 30% recycled polyester should be washed on a delicate cycle at a low temperature and ironed carefully. The adidas jogging bottoms also state that tumble drying should be avoided.

If you wash your sportswear often, it’s worth checking:

  • The care instructions and maximum temperature.
  • Whether the garment is suitable for tumble drying.
  • Whether fabric softener is recommended – it’s not suitable for some synthetic fabrics.
  • Whether to wash the garment inside out to protect logos and prints.
  • Whether cotton fabrics may shrink.

Important specifications to check before you buy

Material and intended use

For training and football, lightweight synthetic fabrics are often practical thanks to their low weight and quick-drying properties. According to the product information, the Under Armour Men’s Tricot Jogger is made from 100% polyester and features a tapered leg, pockets and an adjustable waistband.

Cotton can feel more comfortable for everyday wear. According to its product page, the Nike Sportswear Club T-Shirt is made from 100% cotton and has a classic fit. The North Face men’s T-shirt is also described as 100% cotton and has a regular fit.

Fleece products provide an extra layer on colder days. According to the available information, the adidas Trefoil Essentials Crew Sweatshirt is made from 70% cotton and 30% recycled polyester. Under Armour’s women’s fleece shorts use a blend of 80% cotton and 20% polyester and have a looser fit.

Fit and freedom of movement

Look out for the difference between:

  • Slim fit: sits closer to the body.
  • Regular fit: offers a more standard balance of comfort and shape.
  • Loose fit: gives you extra room, for example when relaxing.
  • Tapered fit: narrows towards the ankle.

A slim fit can work well for a smart casual outfit, but it may not feel comfortable for everyone when moving around. A loose fit is comfortable at home, but may be less practical for some types of training. For men’s training trousers, an adjustable waistband, plenty of room to move and a suitable leg length are important things to check.

Construction and practical details

As well as the material, check for:

  • An elasticated waistband with a drawcord.
  • Ribbed cuffs and hems.
  • Side pockets or a secure pocket for your phone and keys.
  • The collar type and neckline finish.
  • Sleeve, trouser leg and inside leg lengths.
  • The placement and finish of logos and prints.

For men’s boxer shorts, pay particular attention to the waistband, the amount of stretch and the fabric composition. The Reebok Sports Brief Wiggins is sold as a 3-pack and is designed for sport and everyday wear. Exact care instructions may vary by version, so check the label.

Frequently asked questions about sportswear and casual clothing

Which fabric is suitable for sportswear?

It depends on how you’ll use it. Polyester is often chosen for lightweight sportswear and training trousers because of its low weight. Many people find cotton comfortable for everyday wear. A cotton-fleece blend can be a good option for comfortable leisurewear. Always check the exact composition on the product page and label.

How do I choose the right clothing size online?

Measure your chest, waist or hips and compare the figures with the size chart for the specific product. Check the fit too: slim, regular, loose or tapered. If you’re between sizes, consider whether you’d prefer more room to move or a closer fit.

How can I keep sportswear in good condition for longer?

Follow the care label, wash dark clothing separately and turn garments with prints or embroidery inside out. Use the recommended temperature and avoid tumble drying if the care instructions say to. This helps reduce unnecessary wear, shrinkage and loss of shape.
