A T-shirt may seem like a straightforward purchase, but small differences in material, fit and sizing determine whether you wear it regularly or leave it at the back of your wardrobe. This applies to men's and women's T-shirts, as well as children's and baby T-shirts.
When shopping online, don't just focus on colour and brand name. Marketing terms such as “extra soft”, “premium” or “antibacterial” only mean something if you can verify them in the product information. A brand's own research may support a particular claim, but that is not a general guarantee for every wearer or situation. So first check the exact composition, sizing information and care instructions.
A T-shirt may look loose or fitted in the product photo. Without chest, waist or body measurements, it can be difficult to choose the right size. The fit can vary considerably between brands, particularly for children's clothing.
So check:
“Soft” and “breathable” are subjective descriptions. The fibre composition is easier to verify. For example, a 100% cotton T-shirt is different from a shirt made with a cotton blend, elastane or synthetic fibres.
Also look at the fabric weight, neckline finish and seams. Lightweight fabric can feel comfortable in warm weather, but may be more prone to showing through or wearing out. Heavier fabric can offer more structure, but may feel warmer.
A T-shirt worn every day is washed frequently. So check the care label in advance. The product information for the Calvin Klein Smooth Cotton T-Shirt states 100% cotton, do not tumble dry and iron at a low temperature. The instructions on the actual label remain the definitive guide, as care requirements can vary between versions.
For a basic T-shirt for everyday wear, the following points are useful:
For babies and children, fabric softness is important for comfort. Also check that seams, labels and neck openings are not unnecessarily stiff. A long-sleeved baby T-shirt can be useful as an extra layer, while a short-sleeved T-shirt is better suited to warmer days.
A crewneck T-shirt has a round neckline and is easy to style. A short-sleeved T-shirt works well under a cardigan, jacket or shirt. A long-sleeved T-shirt offers more coverage and can be worn as a mid-layer in spring and autumn.
Look at the neck ribbing: it should sit neatly without feeling tight. For children's clothing, a generous neck opening is practical when getting dressed and undressed. For baby and toddler styles, check that the fastening and sizing are specified in the product description.
A black T-shirt and a white T-shirt are easy to pair with jeans, shorts, chinos or a skirt. Light colours can show stains more quickly; with dark colours, it is important to follow the washing instructions to help preserve the colour as well as possible.
If you're unsure, start with a neutral colour and a classic cut. This increases the chance that the shirt will work with several outfits.

We've put together a complete, up-to-date list of products that fully meet these strict selection criteria and the applicable European safety regulations.
For a men's or women's T-shirt, measure a shirt that fits comfortably and compare its width and length with the product information. Don't automatically choose the same size from every brand. An S may fit differently from one style to another.
For children, you can follow this order:
For a baby T-shirt, age is only an indication. For example, the Chicco size guide lists sizes for 0, 1, 3, 6, 9 and 12 months, plus children's sizes up to 12 years. Always check the current table for the product you've selected.
Wash a cotton T-shirt according to the label and separate dark and light colours. Only use a tumble dryer if the care label allows it. The product information for the Calvin Klein style states that it should not be tumble dried and can be ironed at a low temperature.
If the label permits, wash a black T-shirt inside out. Don't leave a shirt damp for a long time after washing. This helps reduce unnecessary strain on the fabric, colour and seams. With children's clothing, it's a good idea to check after every wash that the neckline and seams are still sitting properly.
It depends on how it is used, perspiration and stains. A shirt worn directly against the skin is usually washed after one wear. A T-shirt worn as an extra layer over a vest may sometimes be worn for longer. Always follow the care label.
100% cotton is a clear material choice for anyone looking for a soft and breathable feel. However, it can shrink or crease if washed or dried incorrectly. So check the care instructions and follow the guidance on the garment label.
Short sleeves are practical for warmer days and as a layer under a cardigan or jacket. Long sleeves are more useful in cooler weather or when you want more coverage. For children and babies, room for movement, straightforward sizing and easy dressing and undressing are also important.
