Buying clothes online: how to choose comfortable clothing in the right size

Buying clothes online may seem straightforward, but the wrong size, unclear material information or an overly flattering product photo can quickly lead to a disappointing purchase. This applies to women’s clothing, men’s underwear, children’s clothing and printed T-shirts.

These practical checks will help you compare products more carefully and find clothing that suits your needs, size and budget.

Common pitfalls when buying clothes online

1. Relying solely on the standard size

A size M or 40 can vary from one brand and model to another. A close-fitting dress will fit differently from a loose women’s loungewear set. With children’s clothing, size 104 may also be linked to an age indication, even though height is often more important.

So always check:

  • The size chart for the specific product.
  • Chest, waist and hip measurements where available.
  • The stated height for children’s clothing.
  • Whether the fit is described as close-fitting, regular or loose.

2. Mistaking marketing language for verifiable information

Words such as “ultra-comfortable”, “perfect fit” and “sustainable” do not tell you much without technical details. Instead, look at the fibre composition, number of pieces, fastening, design and care instructions.

According to Reebok’s own information, the RBK Sports Trunks are designed for everyday wear, sport and an active lifestyle. This is a brand description; you can assess it in practical terms by looking at the elasticated waistband, design and available size.

3. Checking care instructions only after purchase

A garment may be attractively priced but require more maintenance than expected. Before buying, check whether the item is machine washable, what temperature it should be washed at and whether it can go in the tumble dryer. Instructions can vary from product to product, particularly for elastane, printed clothing and delicate fabrics.

The key specifications to check

Material and feel

For comfortable clothing, the composition is an important starting point. For example, a T-shirt made from 95% cotton and 5% elastane offers stretch according to the stated product information. This makes it relevant for everyday wear, but it does not automatically indicate how every wearer will experience the material.

For women’s loungewear, a double gauze structure may appeal to anyone looking for a soft, loose-fitting set. For men’s boxers, an elasticated waistband, the design and freedom of movement are practical points to consider. Always check that the material information is actually shown on the product page or label.

Sizing and fit

Use a flexible tape measure when taking your measurements and wear thin clothing. Do not pull the tape too tightly. Then compare the results with the product’s chart, rather than relying solely on your usual size.

Different categories require attention to different points:

  • Women’s dress: chest, waist, hips and overall length.
  • Men’s underwear: waist measurement and whether you want a close-fitting or looser fit.
  • Children’s leggings: height, waist and freedom of movement.
  • Band T-shirt: chest measurement, international size and preferred style of wear.
  • Clothing in different sizes: check whether EU, INT, UK or brand sizes are being used interchangeably.

Care and frequency of use

For everyday wear, care instructions are at least as important as appearance. The Reebok trunks and Wrangler trunks, for example, specify machine washing, no bleaching, no tumble drying and ironing at a low temperature. Always follow the product label, as the composition or finish may vary from one item to another.

Frequently asked questions about buying clothes online

How do I determine my size when buying clothes online?

Measure your chest, waist and hips where necessary, then compare these measurements with the product’s size chart. Use age only as a guide for children’s clothing. Height and body measurements usually provide a more useful starting point.

How long will clothes bought online stay looking good?

This depends on the material, how often the item is worn and how it is cared for. Wash it according to the label, do not use bleach unless permitted and avoid the tumble dryer when the product instructions advise against it. Printed clothing may benefit from being washed inside out, but always follow the specific instructions.

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

It varies by product, brand and offer. Do not compare the price alone; also consider the number of items, delivery costs, material, size availability and returns terms. For example, a 3-pack of men’s boxers may work out differently from three individual items.
