Buying T-shirts and sweatshirts: how to choose the right style and avoid a poor purchase

Choosing a new item of clothing may seem straightforward, but small differences can make a big difference when it comes to T-shirts and sweatshirts. The wrong size, unclear fabric composition or a fit that does not suit how you plan to wear it can quickly lead to a disappointing purchase. This applies to men's T-shirts, children's T-shirts, long-sleeve T-shirts and hoodies.

Joybuy Product Recommendation Officer therefore encourages you to focus above all on verifiable information: sizing, material, sleeve length, care instructions and intended use.

Common pitfalls when buying T-shirts and sweatshirts

1. Confusing a brand name with the right fit

A Nike T-shirt, Adidas T-shirt or Tommy Hilfiger sweatshirt may look appealing, but a well-known brand name does not automatically mean that a garment will fit well. Look out for terms such as regular fit, slim fit and athletic fit. A slim-fit style is narrower than a classic style and may be less suitable if you need plenty of freedom of movement.

For children's clothing, the stated age is only a guideline. It is better to check the child's height and chest measurement in the size guide.

2. Interpreting material claims too broadly

“Cotton” can refer to a range of properties. A cotton T-shirt often feels different from a polyester sports top or a blended fabric. Always check the exact composition. The Adidas Adicolor Classics 3-Stripes Tee, for example, is described as 100% cotton. The Nike Sportswear Club T-shirt is also listed as 100% cotton.

For a sweatshirt made from organic cotton, it is important to check whether the product information actually lists organic cotton as the main material. The Tommy Hilfiger ESSENTIAL SWEATSHIRT Kids lists organic cotton as its main material. Other sustainability factors, such as production conditions or certification, are not automatically proven by this alone.

3. Overlooking care instructions

A T-shirt can shrink or lose its shape if it is washed at too high a temperature. Always check the care label and look for instructions on washing temperature, drying, ironing and bleach. Several models in this overview are listed as suitable for washing at a maximum of 30 °C or on a gentle cycle. Always follow the instructions on the actual product label, particularly for children's clothing.

The key specifications to check

Size and fit

For adults, it is best to measure your chest and compare it with the size guide. The same letter size can fit differently depending on the T-shirt model. The Nike Sportswear Club T-shirt is described as having a classic fit and offers a relaxed silhouette. The Adidas Adicolor model, on the other hand, has a slim fit.

For children's T-shirts, height in centimetres is often the clearest indication of size. The Chicco Long Sleeve T-Shirt in size 74 is intended for a height of 74 cm. For older children, the listed sizes extend to 110, 116, 122, 128, 140 and 152 cm, depending on the model.

Sleeve length and intended use

  • Short sleeves: suitable for everyday wear, layering and plenty of freedom of movement.
  • Long-sleeve T-shirts: practical in changeable weather or under a sweatshirt.
  • Sports T-shirts: check breathability, weight and the exact fibre composition.
  • Sweatshirt: provides more coverage, but is less suitable for intense exercise if the fabric does not wick away heat and moisture effectively.
  • Hoodie: as well as the material, check the hood, hem and pockets.

According to Nike's product description, Dri-FIT technology is designed to manage moisture. This is a brand claim rather than a universal guarantee. For sportswear, it is also sensible to check the specific material composition and fit.

Material and care

A cotton T-shirt is often suitable for casual wear and layering. Polyester may be used in sportswear because of its low weight and moisture management, as claimed by the brand in the product description. A sweatshirt made from organic cotton is described as soft in the product information, but its lifespan also depends on the seams, hems, how often it is washed and how it is dried.

Frequently asked questions about T-shirts and sweatshirts

What is the difference between a T-shirt and a long-sleeve T-shirt?

A T-shirt usually has short sleeves. A long-sleeve T-shirt has long sleeves and can be worn on its own or as a layer under a sweatshirt, jacket or hoodie. With a white long-sleeve T-shirt, check that the fabric is sufficiently opaque for the look you want.

Which material is suitable for sports?

That depends on the activity and your preference. Cotton feels familiar and comfortable for everyday wear, while polyester is often used in sports T-shirts. According to Nike's product description, Dri-FIT was developed for moisture management. Always check the exact composition, fit and washing instructions as well.

How long will a T-shirt or sweatshirt last?

Its lifespan depends on the quality of the seams and fabric, how often you wash the garment and how you dry it. Washing according to the label, washing similar colours together and using low drying or ironing temperatures can help preserve its shape and colour for longer. Choosing the correct size also prevents unnecessary strain on seams and hems.
