Buying clothes online may seem straightforward, but an attractive product photo does not always tell the whole story. A T-shirt may be thinner than expected, trousers may fit differently depending on the cut, and sizing for underwear is not always consistent between brands. Terms such as “soft”, “durable” and “breathable” only become meaningful when you check the material composition, size guide and care instructions.
Use these practical selection criteria to compare clothing more effectively. That way, you can find everyday clothing suited to how you use it, your budget and your preferences for cotton, well-known brands or multipacks.
A size S, M or XL is not a fixed standard. Always check the chest, waist and hip measurements in centimetres. For example, the Adidas Trefoil Essentials Tee JI8545 Black S lists a chest width of 48 cm. That is more specific than relying on the letter S alone.
Also consider the type of fit:
A garment containing cotton may also include polyester or elastane. That is not necessarily a disadvantage, but it does affect how the garment feels, its stretch and how it should be cared for. According to the product information, the Reebok Crew Neck Tee consists of 60% cotton and 40% polyester, while the Adidas Adicolor Classics 3-Stripes Tee is described as 100% cotton.
If you are specifically looking for cotton shirts, it is worth reading the full composition. For men’s shirts or heavier cotton clothing, the fabric weight is also relevant. According to the product description, the LEE 7 1/4OZ NS Cotton Shirting has a heavier cotton fabric and a non-stretch structure.
Words such as “antibacterial”, “hypoallergenic” or “durable” require additional scrutiny. Do not treat such claims as guaranteed results. According to Utree’s product information, the gusset of certain models contains a cotton material with an “10A antibacterial” property, as stated by the seller. This is a claim from the product description; it is not a medical assessment or a guarantee of a personal benefit.
When choosing everyday underwear, focus on verifiable details such as the fabric composition, rise, seams, size range and washing instructions.
For comfortable everyday clothing, 100% cotton, cotton-modal and cotton blends are common choices. Cotton feels familiar and can be comfortable for T-shirts, jogging bottoms and underwear. Modal or elastane can provide added softness and flexibility. However, check whether you are looking for a sturdy, shape-retaining fabric or a more stretchy fit.
For women’s and men’s underwear, the leg openings, waistband and lining are also important. An underwear multipack can be practical for everyday use, but compare the price per item and check whether all the pieces have the same composition.
Use a garment you already find comfortable as a reference. For example, measure the chest width of a well-fitting men’s T-shirt or the waist of a pair of jogging bottoms. Then check the size guide for the new model.
When choosing trousers, look at:
According to the product information, the LEE PANT WOVEN YUKON has a drawstring waistband and deep pockets. This makes the trousers practical for wearing at home and for casual use, but the size should still be matched to the stated measurements.
The washing instructions indicate how to preserve the colour, shape and fabric as effectively as possible. For example, a black T-shirt may be best washed inside out with similar dark colours. Some products should not be tumble-dried.
Before buying, check:
A minimum two-year legal guarantee applies to many consumer products in the EU, but normal wear and tear or damage caused by incorrect care may be assessed differently. Therefore, keep the product information and follow the care label.

We have put together a complete, up-to-date list of products that fully meet these strict selection criteria and the applicable European safety regulations.
Measure your chest, waist or hips with a flexible tape measure and compare these measurements with the size guide for the specific product. Also consider the fit and fabric: a slim fit without stretch will feel different from a regular fit made from an elasticated cotton blend.
That depends on the price per item, material and how often you intend to use it. Divide the total price by the number of items and check whether all pieces have the same size, cut and composition. A 3-pack can be practical for everyday rotation; disposable underwear is mainly intended for travel or temporary use.
Always follow the care label. Ideally, wash dark cotton shirts with similar colours, use a mild detergent and avoid tumble-drying if this is advised. Washing garments inside out helps protect those with a print or logo. For organic cotton clothing, also check the brand’s specific care instructions.
