Buying clothes online: how to choose comfortable clothing without making a mistake

When you’re buying clothes online, you often look at the brand, colour and price first. However, it’s the fit, fabric and care instructions that really determine whether a garment stays comfortable in everyday use. A nice product photo doesn’t always tell you enough about the material, sizing or suitability for sport.

With this practical selection guide, you can compare men’s T-shirts, women’s clothing, sports tops, casual wear and comfortable clothing in sizes S, M and L.

Common pitfalls when buying clothes online

1. Confusing a size label with a fixed size

A size M can fit differently depending on the brand and style. An Adidas T-shirt with a slim fit feels different from a T-shirt with a relaxed fit. International size markings can also cause confusion. Always check the size guide, chest measurement and any information such as “true to size” or “loose fit”.

2. Only looking at the fibre composition

“100% cotton” can feel comfortable, but it doesn’t automatically tell you about the thickness, stretch or shape retention. A shirt made from 160 gsm cotton feels different, for example, from a thin polyester sports top. Also pay attention to the weave, collars and seams. These elements affect how a garment hangs and how it holds up after washing.

3. Treating marketing claims as guarantees

Terms like “breathable”, “antibacterial” or “stays in shape” shouldn’t be taken as guaranteed results without checking. Look for verifiable information such as material, fit, washing instructions and product measurements. According to Nike’s own information, Dri-FIT is designed to wick away moisture; the practical experience can vary depending on the activity and the individual.

Three parameters to check before you buy

Fit and measurements

First, choose the desired style:

  • Slim fit: sits closer to the body, like the Adidas Adicolor Classics 3-Stripes Tee.
  • Regular fit: offers more room to move without being noticeably loose.
  • Relaxed fit: is looser and suitable when you prefer extra space.

At home, lay a well-fitting shirt flat and measure it. Compare the chest width with the product information. For the Adidas Adicolor Classics 3-Stripes Tee, for example, a chest width of 48 cm is listed for the chosen size. The North Face provides chest, waist and hip measurements for each size.

Material and intended use

For everyday wear, cotton and cotton blends are often a logical choice. Cotton generally feels soft, while polyester dries quickly and is often used in sports tops. A Nike Dri-FIT shirt can therefore be suitable for football, walking or light training. However, check the full material composition: the product information for this model lists both 100% polyester and a blend of 57% cotton and 43% polyester. If the information is contradictory, it’s wise to follow the current product page and the care label.

Care and durability

Washing instructions are practical information, not an afterthought. Pay attention to:

  • maximum washing temperature;
  • whether or not to tumble dry;
  • use of bleach;
  • ironing around prints;
  • washing dark colours separately.

The Adidas product information recommends a gentle wash programme at a maximum of 30 °C, no bleach and careful handling of the print. The North Face advises washing the T-shirt in question at a maximum of 40 °C, with similar colours and air drying. By following these instructions, you can minimise shrinkage, colour fading and damage.

Also relevant: women’s clothing and layering

For a women’s everyday wardrobe, alongside a women’s blouse-style top, you could also look at a women’s sweatshirt or a seamless bralette as a base layer. With a bralette, strap width, cup construction and band size are more important than just the letter size. The Utree top has built-in, semi-fixed pads and is available in sizes including M and L. The manufacturer also mentions stretch material and a square neckline. Claims about odour, antibacterial properties or protection against dust mites should be interpreted according to the brand’s information, not taken as guaranteed effects.

For layering, a soft top in a neutral shade is practical under a cardigan, blazer or blouse. For each garment, check whether the size matches your own body measurements and whether returns are possible if the fit isn’t right.

Frequently asked questions about buying clothes online

How do I determine my clothing size when ordering online?

Measure your chest, waist and hips at the widest point and compare these values with the size guide for the specific product. Also look at the fit. Sizes S, M and L are not fully standardised between brands.

Which material is suitable for sport and everyday use?

Polyester or a cotton blend can be practical for sport due to its low weight and drying properties. Cotton feels comfortable for many people in everyday wear. The right choice depends on the activity, temperature, fit and care.

How can I make clothes bought online last longer?

Follow the care label, wash dark colours separately and don’t use bleach when it’s not recommended. Air-dry clothing if the product information doesn’t advise tumble drying. Also check prints, collars and seams before you complete a purchase.
