Buying designer clothes online: how to choose affordable clothing that suits you

Buying designer clothes online might seem straightforward, but a nice product photo doesn't tell the whole story. The fit can turn out differently than expected, a fabric can be less versatile than you thought, and a low price says nothing about how it wears. With a few simple checks, you can avoid a bad purchase and find clothes that fit your everyday life.

Common pitfalls when buying clothes online

1. Relying only on the size letter

A size M isn't the same across every brand. A women's dress in size M can fit differently to a T-shirt in size M. Always check the size guide, chest measurement and fit. Also look out for terms like slim fit, regular fit or relaxed fit.

A product in size 40, such as the JDY dress, isn't automatically comparable to an M or L from another brand. The specific product size and its corresponding measurements are more important than the letter on the label.

2. Skipping the material and care instructions

A cotton T-shirt can be comfortable for everyday wear, but the care advice differs from product to product. Check the washing temperature, drying instructions and guidance around prints. A black T-shirt, for example, can bleed colour if it isn't washed according to the instructions.

With denim, it's also worth looking at the shape and weight of the fabric. A denim dress for women can look casual, but for warm weather you'll also want to know whether the fabric offers enough freedom of movement.

3. Confusing a versatile design with a suitable occasion

An ONLY dress or JDY dress can be easy to style, but not every cut works for the office, a day out and a formal occasion all at once. Look at the length, neckline, colour and how it can be paired with trainers, sandals, boots or accessories.

A versatile garment is especially valuable when you know in advance how you want to wear it.

What to look for when buying designer clothes online

1. Fit and sizing

Use the size guide for the specific product. When it comes to T-shirts, pay attention to:

  • chest width and total length;
  • the difference between slim fit and relaxed fit;
  • the amount of room you want at the shoulders and sleeves;
  • differences between EU, UK and US sizes.

With the adidas Adicolor Classics 3-Stripes Tee, size M is listed as EU size 46, with a stated chest width of 48 cm. Always check whether the size on the product page matches the size you normally wear.

For women's dresses, the waist, hips and length are often at least as important as the size letter. The available options in this selection include S, M, L and size 40.

2. Material and construction

Don't just look at the brand name – check the product specifications too. A T-shirt made from 100% cotton has different properties to a blended fabric. The adidas T-shirt for men in this selection is described as being made from 100% cotton and features a ribbed round neck and cuffs.

The North Face T-shirt for men is described in the product information as a model made from 160 gsm cotton jersey fabric. The fit is relaxed, so slightly roomier. That can be handy for layering or casual wear, but less suitable if you're after a close-fitting silhouette.

3. Care, colour and use

Check before you buy whether the garment fits with your washing routine. Examples from the product specifications:

  • wash dark colours separately or with similar colours;
  • use a mild detergent;
  • avoid bleach;
  • air-dry certain cotton T-shirts;
  • do not iron directly over a print;
  • always follow the care label on a denim dress for women.

Care partly determines how a garment keeps its appearance. According to the product information, the statutory consumer warranty for the adidas model is at least two years within the EU; additional rights may apply under national law.

Frequently asked questions about buying designer clothes online

How do I determine which clothing size I need online?

Compare your body measurements with the size guide on the product page. Pay attention to chest, waist and hip measurements, and check the fit. A slim fit T-shirt fits differently to a relaxed fit model. With international sizes, also look at the EU conversion.

How long does a cotton T-shirt last?

The lifespan depends on how often you wear it, the wash programme, temperature and drying method. Wash according to the label, use a mild detergent and avoid bleach. For printed items, washing inside out and not ironing directly over the print is practical.

Is a black T-shirt or white T-shirt easier to style?

Both colours are versatile. A black T-shirt, like the adidas model, works well with dark jeans and neutral trousers. A white T-shirt, like the The North Face model, suits denim, shorts and layering. Choose based on your existing wardrobe and the care you prefer.
