Buying designer clothing online: how to choose clothes that suit your style and needs

Buying designer clothing online might seem straightforward, but an attractive photo and a well-known brand name don't tell the whole story. Making the right choice also depends on the fabric, fit, care instructions, and how you plan to wear the garment. This applies to women's clothing, men's clothing, underwear, and comfortable leisurewear.

Pay particular attention to these common pitfalls:

• Relying solely on the brand: a famous name says nothing about how it will fit your body or the fabric of a specific style.
• Choosing the wrong size: a slim-fit shirt fits differently to a regular-fit jacket. So don't just look at S, M or L – also check the size guide and the cut.
• Ignoring care instructions: a jacket that requires hand washing takes more time than a machine-washable T-shirt. This can affect how often you wear it day to day.
• Taking marketing claims at face value: terms like "breathable", "sustainable" or "moisture-wicking" may come straight from the product description. Treat them as information from the brand and always check the actual fabric composition and care details.

The key specifications for designer clothing

1. Check the fabric composition

The fibres largely determine how a garment feels and how it should be cared for. Cotton can be comfortable for T-shirts, shirts and underwear. Elastane adds stretch, while polyester is often used in linings, jackets and sportswear.

Examples from product information:

• The Tommy Hilfiger Heritage trench coat has an outer fabric of 100% cotton twill and a polyester lining.
• The Calvin Klein bikini 3-pack is made from 95% cotton and 5% elastane.
• The Diesel hoodie is described as being made from 100% cotton.
• The Reebok T-shirts are made from 60% cotton and 40% polyester.

A higher cotton content doesn't automatically mean a garment is more comfortable for everyone. Also consider the thickness, stretch, lining and fit.

2. Choose the fit based on how you'll wear it

A regular fit generally offers more room to layer over other clothing. A slim-fit shirt is more fitted and works well with a smart outfit, but may not be ideal if you need plenty of freedom of movement.

When shopping online, look out for:

1. The stated fit: slim, regular or relaxed.
2. The brand's size guide.
3. The shoulder width, chest or waist measurements when available.
4. Whether you plan to wear the garment over a T-shirt, blouse or jumper.

For underwear, the waist or hip measurement is more important than just the letter size. An elasticated band that's too tight can be uncomfortable, while one that's too loose won't stay in place properly.

3. Consider care instructions and how you'll use it

The care instructions give a more realistic picture of everyday convenience than any commercial slogan. An item that can be machine washed at a low temperature may be better suited to regular use than a garment that requires specialist cleaning.

Examples:

• The Calvin Klein bikini 3-pack can be machine washed and tumble dried on a low setting, according to the product information.
• The U.S. Polo Assn. jacket requires hand washing and should not be tumble dried.
• The Lee crop top should be washed at 30 °C and must not be ironed.
• The Calvin Klein hoodie and Diesel hoodie work well as a layer over a T-shirt or as a standalone casual piece; always check the full care information on the product page before purchasing.

Frequently asked questions about buying designer clothing online

What should I look for when buying designer clothing online?

First, check the product name, size, fit, fabric composition, colour and care instructions. Then look at the returns policy and check whether the chosen style is suitable for how you'll use it. A Tommy Hilfiger trench coat, for example, involves different considerations to Calvin Klein underwear or a hoodie.

How can I tell if a clothing size will fit when buying online?

Use the size guide on the product page and compare it with a garment that already fits you well. With women's and men's clothing, also pay attention to the cut: slim fit, regular fit and relaxed fit can all fit differently within the same letter size.

Does designer clothing last longer than unbranded clothing?

Not automatically. The lifespan depends on the fabric, seams, construction, how you wear it and how you care for it. So check the fibre composition and washing instructions. Wash at the recommended temperature, avoid unnecessary tumble drying and always follow the label.
