Buying clothes and shoes online: how to choose wisely and avoid a poor purchase

Buying clothes and shoes online may seem straightforward, but an attractive product photo does not always tell you enough. A jacket may be described as waterproof without clear technical specifications. A shoe may look comfortable but turn out to be narrow-fitting. And when it comes to underwear or socks, a brand name says little about the fit you need.

With these practical checks, you can compare clothing, underwear and shoes based on the features that really matter in the UK: material, sizing, intended use, care requirements and overall value.

Common pitfalls when buying clothes online

1. Confusing marketing language with verifiable specifications

Words such as “breathable”, “durable” or “antibacterial” sound clear, but are difficult to compare without further explanation. So look at the material composition, construction and sizing information. For an outdoor jacket, for example, it is useful to know what type of fabric is used, whether it has a lining and how much room there is for an extra layer.

Claims about performance should be read carefully. According to a brand’s own research or product information, a particular finish may help wick away moisture, but that is not automatically a guarantee for every user or situation.

2. Relying solely on the standard size

Sizing varies by brand, model and fit. A size L T-shirt may fit differently from a size L jacket. For clothing, check the chest, waist and hip measurements. For shoes, foot length in centimetres is often more useful than the European shoe size alone.

Also consider the shape of the product. Slim-fit boxer shorts fit differently from relaxed-fit trunks. With a unisex hardshell jacket, choosing a larger size may be practical if you want to wear a fleece or thick jumper underneath.

3. Ignoring care requirements and intended use

A garment that can only be hand-washed requires more time than a machine-washable clothing multipack. Before buying, check the washing instructions, drying method and sensitivity to heat. Leather shoes require different care from textile or synthetic trainers.

The most important specifications to check

Material and comfort

For everyday use, cotton, elastane and technical synthetic fibres are common choices. Cotton generally feels soft and is often used for men’s underwear, women’s underwear, cotton socks and T-shirts. Elastane provides stretch, but the percentage also affects how snug or flexible a garment feels.

For sports and outdoor activities, moisture management, ventilation and freedom of movement are important. With sports socks, look at the cuff, heel construction and toe seam. A flat or seamless toe can help reduce pressure points, but fit is still a personal matter.

Size, cut and room for movement

Use the size chart for the specific product. For example, the PELLIOT jacket lists the length, chest measurement, shoulder width and sleeve length for each size. According to the product information, the chest measurement ranges from 108 cm for XS to 130 cm for XXL. If you plan to wear several layers underneath, choose your size accordingly.

For men’s boxer shorts and women’s briefs, waist and hip measurements are more important than simply choosing S, M or L. Also check whether the model is low rise, regular fit, slim fit or relaxed fit.

Shoe size, last and sole

For trainers, walking shoes, women’s boots and casual shoes, check:

  • foot length in centimetres;
  • the width or stated last;
  • the material of the upper, lining and sole;
  • the fastening, such as laces or elasticated panels;
  • the tread and grip of the outsole.

A lightweight trainer with mesh and an EVA midsole, for example, is more suitable for commuting or everyday use than a heavy walking shoe. Not every trainer is suitable for wet conditions, so look for an explicit description of water resistance or waterproofing.

Comparing underwear and socks with a clear purpose

For everyday comfort, the seams, waistband and composition are more important than appearance alone. The Calvin Klein Icon Cotton Stretch boxer shorts are offered as a 3-pack made from cotton and elastane. According to the product information, the Reebok Carina women’s briefs consist of 95% cotton and 5% elastane. Details like these help with comparisons, but they do not by themselves tell you how a particular style will feel on your body.

When choosing cotton socks for the office or leather shoes, look for:

  • a size range that matches your shoe size;
  • an elasticated cuff that stays in place;
  • a heel construction that does not slip;
  • care at low temperatures;
  • a multipack if you are looking for several identical pairs.

For sports, sports socks with a more reinforced heel and toe area are often more practical than thin formal socks. Also check whether claims such as “antibacterial” come from the brand’s product information and whether a specific standard or testing method is mentioned.

Frequently asked questions about buying clothes and shoes online

How do I determine my size when buying clothes online?

Measure your chest, waist and hips with a flexible tape measure, then compare these measurements with the size chart for the specific item. For shoes, measure both feet at the end of the day and use the longer foot as your reference. Also check the stated fit, such as regular, slim or relaxed fit.

Is a waterproof jacket suitable for everyday use?

That depends on its construction, ventilation, seams, fastenings and care requirements. An outdoor jacket or unisex hardshell jacket may be suitable for commuting and walks, but check the product details before assuming that the model is intended for prolonged heavy rain or intensive mountaineering.

Are clothing multipacks better value?

A multipack can reduce the price per item and is practical for basics such as T-shirts, men’s boxer shorts, women’s briefs or socks. However, compare the total price, material percentages, available sizes and washing instructions. A lower price per item is less appealing if the fit does not suit you or the care requirements take up a lot of extra time.
