How to buy clothes online without getting it wrong: choosing women’s and men’s clothing that suits your needs

Buying clothes online is convenient, but a product photo does not tell you everything. A shirt may look roomy on screen yet come up narrow. A sweatshirt may look soft, while barely any information is provided about its composition. Even well-known brands such as Adidas and Nike do not automatically indicate the right fit for you.

This practical checklist helps you focus on the points that make the biggest difference when buying women’s clothing, men’s clothing, sportswear and casual clothing.

Common pitfalls when buying clothes online

1. Relying only on the size letter

A size M or L is not a fixed standard. An Adidas T-shirt in size M may fit differently from a women’s blouse in size M. So pay attention to:

  • the stated fit: slim, regular or oversized;
  • chest width, length and sleeve length;
  • the size guide for the specific product;
  • differences between EU, UK and US sizes.

For example, the Adidas Adicolor Classics 3-Stripes Tee is listed in size M, with a chest width of 48 cm. The product information also specifies a slim fit. These are more concrete indications than the letter M alone.

2. Confusing marketing language with product features

Terms such as “breathable”, “durable” or “waterproof” can have different meanings. Always check whether the product page specifies a material, construction or intended use.

The PELLIOT long-sleeved top is described as waterproof and durable in the product title. As this information comes from the product listing, it is best treated as a feature to verify further on the product page, rather than as a guarantee for every weather condition.

Nuance is important with sportswear too. According to Nike’s product information, Dri-FIT technology is designed to help wick moisture away. The description also mentions lightweight material and freedom of movement. The exact fabric information deserves attention: the description states 100% polyester, while the product specifications state 57% cotton and 43% polyester. If in doubt, check the current details before buying.

3. Skipping the care instructions

A garment may fit well, but incorrect washing can quickly cause it to lose its shape or colour. Before ordering, check:

  • the maximum washing temperature;
  • whether or not it can go in the tumble dryer;
  • ironing instructions;
  • whether it should be washed with similar colours;
  • instructions for prints and specialist fabrics.

For the Adidas T-shirt, a delicate wash programme and a maximum temperature of 30 °C are specified. Bleaching and dry cleaning are not recommended. Dark colours should be washed separately or with similar colours.

Three parameters you should always check

Fit and measurements

Do not choose clothing based solely on your usual size. Lay a shirt that fits comfortably flat on a table and compare its chest width and length with the product details. With clothing in sizes M and L, the difference between a slim fit and a regular fit is particularly important.

For women’s clothing, such as a long-sleeved top or cardigan, also check the shoulder line and sleeve length. With men’s clothing and sports shirts, room around the chest and arms is often more important than a close-fitting silhouette.

Material and intended use

The material determines how a garment feels and what it is most practical for.

  • Cotton usually feels familiar and comfortable for casual clothing and everyday wear.
  • Polyester is often used in sportswear because it is lightweight and has properties linked to moisture management in product descriptions.
  • Wool blends may be suitable for cardigans and layering, but require extra care and attention.
  • Stretch fibres provide greater freedom of movement, but also check whether the fabric feels sufficiently sturdy.

A cotton T-shirt is a sensible choice with jeans and for everyday wear. A sports shirt made with synthetic fibres may be more practical for football, cycling or travelling. That does not mean one material is suitable for everyone.

Care, guarantee and returns

As well as the price, check the delivery and returns terms. Within the EU, many new products are covered by a legal guarantee; some listed products state a minimum legal guarantee of two years. The precise rights depend on the purchase and the applicable regulations.

Keep the product information and check the garment when it arrives for its size, colour, seams and any damage. Ideally, try it on before washing it, so that you can make use of the applicable returns terms if it does not fit.

Frequently asked questions about buying clothes online

How do I determine my clothing size when ordering online?

Measure a garment that fits well and compare its chest width, length and sleeves with the size guide on the product page. Also pay attention to the fit. A slim fit feels different from a regular fit, even when both use the same size letter.

Which clothing is practical for everyday wear?

For everyday wear, T-shirts, long-sleeved tops, sweatshirts and cardigans are easy to combine. Choose a material and fit that suit your routine. Cotton often works well for casual outfits; for sport or intensive exercise, focus particularly on weight, freedom of movement and care instructions.

How can I make clothes bought online last longer?

Follow the care label, use the recommended temperature and avoid the tumble dryer when it is not permitted. Wash dark colours separately, turn garments with prints inside out and check that the size and fit are right before washing. This helps reduce the risk of shrinkage, colour differences and damage.
