Buying clothes online: how to choose comfortable, functional clothing without making the wrong purchase

Buying clothes online may seem straightforward, but an appealing photo tells you little about the fit, material or how the garment performs day to day. A sweatshirt may be warmer than expected, for example, while jogging bottoms may fit well around the waist but feel too loose around the legs. Work trousers may have plenty of pockets without being comfortable to move in.

Use these checkpoints to compare clothing based on objective product information. This makes it easier to find comfortable casual clothing for relaxing at home, sport, work or everyday wear.

Common pitfalls when buying clothes online

1. Relying only on the size letter

A size S, M or L is not the same across every brand. Always check the size chart, chest width, waist measurement and inside leg length. Some styles also use American, British or European sizing.

A regular fit feels different from a slim fit. Straight-leg trousers may feel roomier than a tapered style. Always check the measurements and compare them with a garment you already know fits you well.

2. Confusing material names with wearing comfort

“Cotton” does not automatically mean that a garment is thick, soft or breathable. A cotton T-shirt may, for example, be made from a cotton blend. Polyester can be lightweight and easy to care for, but it feels different from fleece or cotton.

So check the fibre composition and intended use:

  • Cotton often feels familiar and comfortable in T-shirts and sweatshirts.
  • Polyester is lightweight and is often used in jogging bottoms.
  • Elastane provides extra stretch, which can be useful in workwear or sportswear.
  • Fleece can provide additional warmth, but requires suitable washing and drying instructions.

3. Failing to match features to how you use the garment

Trousers with cargo pockets are not automatically suitable for heavy-duty work. Check what the pockets, reinforcements and knee pockets are designed for. Clothing for the office, walking and DIY has different requirements.

With work trousers with knee pockets, fit, knee-pad compatibility, freedom of movement and reinforced fabric are all important considerations. For relaxed wear, an elasticated waist and soft fabric are often more relevant.

Which specifications should you check?

Fit and measurements

As well as the size, look at the cut:

  • Regular fit: a standard fit with room to move.
  • Slim fit: cut closer around the legs or torso.
  • Straight leg: a straight trouser leg from top to bottom.
  • Mid-rise: the waist sits around the middle of the hips.

When ordering online, the product size chart should be your main reference. The Adidas Trefoil Essentials Crew Sweatshirt IY4932 Black S, for example, is listed as size S with a chest width of 48 cm. That is more useful than simply seeing the letter S.

Composition and care

Check whether the fabric suits how often you intend to wash the garment. According to the product information, the Adidas sweatshirt is made from 70% cotton and 30% recycled polyester. The soft fleece, crew neck and ribbed trims are designed for everyday wear. The care instructions specify a delicate wash programme and tumble drying at a low temperature.

According to the product information, the Urban Classics Piped Panel Trackpants Track Pants Bottlegreen L is made from 100% polyester. The trousers have an elasticated waist with drawstring, straight legs and ankle cuffs. This makes this style suitable as lightweight training bottoms or as green men's jogging bottoms for casual outfits.

Functionality and safety information

The difference between ordinary trousers and technical workwear is more apparent when it comes to work clothing. According to the product information, the CAT Nexus Knee Pocket Stretch Trouser includes:

  • a composition of 50% cotton, 48% polyester and 2% elastane;
  • ripstop fabric with Cordura reinforcements;
  • a reinforced crotch construction and articulated knees;
  • multiple pockets, including a phone, knife and cargo pocket;
  • Cordura knee pockets suitable for CW91 knee pads;
  • straight legs with a 16-inch opening for work boots.

According to the product information, the reference to EN14404-certified protection applies to compatible knee pads. Always check exactly which component is included and which protection class applies before purchasing.

How to compare clothing for everyday wear

Before placing your order, make a quick checklist:

  1. Fit: compare the size chart with your own measurements.
  2. Material: check the fibre composition and the amount of stretch.
  3. Use: decide whether you need clothing for sport, work, home or layering.
  4. Care: check the washing, drying and ironing instructions.
  5. Returns policy: check the current terms before ordering.
  6. Warranty: in the EU, a statutory guarantee of conformity generally applies; additional terms may vary by product and seller.

For Urban Classics jogging bottoms, for example, the drawstring waist is an important feature, while with CAT work trousers, the pocket layout and knee-pad compatibility are the main considerations. For a men's Reebok T-shirt, the cotton blend and classic crew neck are useful points of comparison.

Frequently asked questions about buying clothes online

How do I choose the right clothing size when ordering online?

Measure your chest, waist, hips and inside leg using a flexible tape measure. Compare these measurements with the chart on the product page. Also consider the fit: regular fit and slim fit can sit differently even when they are the same size.

How long do clothes bought online stay in good condition?

Their lifespan depends on the material, how intensively they are used and how they are cared for. Follow the care label, do not use bleach unless permitted and avoid high drying temperatures when the instructions specify low-temperature drying. This can help everyday clothing retain its shape and colour for longer.

Is buying clothes online cheaper than buying them in a shop?

It depends on the product, brand, delivery costs and any return charges. So do not compare only the purchase price. Also consider the material composition, care requirements, fit, delivery costs and returns policy. A slightly more expensive garment may prove more practical if it suits how you use it better and does not need replacing as quickly.
