Buying clothes online seems straightforward: you pick a size, look at a photo and check out. Yet an attractive product page can hide important details. The wrong size, unclear material information or a fit that doesn't suit your needs can quickly lead to a bad purchase.
With this practical guide, you'll know exactly what to look for when shopping online. Whether you're after men's boxer shorts, a Nirvana T-shirt, kids' leggings, a women's dress or women's loungewear: always check the information behind the marketing claims first.
A size M or 40 isn't the same across every brand. One pair of trousers may be fitted, while another offers more room. With children's clothing, body height can be more important than the age on the label.
So always check:
For example, the Chicco kids' leggings in size 104 include a size reference for approximately four years and a height of 104 cm. The accompanying chest, waist and hip measurements give you more to go on than age alone.
Words like "soft", "breathable" and "skin-friendly" sound nice, but they only mean something if the product specifications back them up. Look at the fibre composition, the construction and the details that directly affect how comfortable something is to wear.
A T-shirt made from 95% cotton and 5% elastane, for instance, has a different level of stretch than a shirt without elastane. With boxer shorts, a flexible waistband, leg length and a smooth finish are the relevant points. According to the product description from Reebok, the model is intended for everyday use and sports activities; that's the brand's product positioning, not a guarantee that the fit will suit every wearer.
A garment that only stays in good condition with a specific wash programme needs more attention than a simple machine-washable model. So check before you buy:
For the Reebok and Wrangler boxer shorts, machine washing is mentioned, but also that bleaching, tumble drying and dry cleaning are not recommended. The label inside the garment is always the final authority, because the composition and finish can vary between different versions.
For comfortable clothing, the material composition is a practical starting point. Cotton feels familiar to many people, while elastane can provide extra stretch. With loungewear, the thickness and weave structure also matter. The Purcotton sets are described as double-layer gauze, knit or AirySoft gauze. Because the full composition isn't listed for every set in the product information provided, it's wise to check the current product page and the wash label before you order.
For casual clothing like an Urban Classics T-shirt or a JDY dress in size 40, don't just look at the chest or waist measurement. Also pay attention to the cut, length and amount of stretch. A dress may be suitable for several occasions, but the exact fit depends on the style and your body proportions.
For sportswear, freedom of movement and a waistband that doesn't dig in are more important than just the look. With men's boxer shorts, the leg length and the position of the seams can determine whether the garment stays comfortable when you're walking, cycling or sitting.
A European product page should clearly show information about the seller, the product and any relevant warnings. For ordinary clothing, a CE marking is not usually the starting point; that marking mainly applies to product categories for which specific European regulations require it, such as certain personal protective equipment. With children's clothing, also check that small parts, cords or decorations are suitable for the age group.
A brand's claim about sustainability, softness or performance should be read as a statement from the brand. According to a brand's own research, such a claim may be backed up, but always check which test, standard or material information is mentioned alongside it.

For a polished outfit, you can compare a women's dress like the JDY Wedgewood in size 40 on size, length and occasion. The product description positions this style as wearable for both daytime and formal events. Check that the size given matches your own body measurements.
If you're mainly looking to relax, you could choose a Purcotton loungewear set. There are versions with double-layer gauze, knit and AirySoft gauze, among others. The sets are available in specific body sizes, such as top 160/84A and trousers 160/68A. So look carefully at the exact variant, because the size label differs from product to product.
Wrangler boxer shorts, a Reebok boxers 3-pack, Urban Classics T-shirts and kids' leggings are also easier to compare when you look at brand, material, fit and care side by side, rather than just focusing on the price.
We've put together a full, up-to-date list of products that fully meet these strict selection criteria and comply with current European safety regulations.
Measure your chest, waist and hips with a flexible tape measure and compare these values with the size chart for the specific product. Use the letter size only as an extra guide. For children's clothing, body height is often an important factor.
That depends on the fibres, seams, print, how often you wear them and how you care for them. Wash according to the label, avoid unnecessarily high temperatures and check whether tumble drying is allowed. Printed clothing generally stays in better condition if you follow the manufacturer's washing instructions.
Choose a fit that gives you enough room to move, check the material composition and pay attention to seams, waistbands and care instructions. For sportswear, stretch and freedom of movement are important; for women's loungewear, the size, fabric structure and desired coverage matter most.
