Buying clothes for women and men: how to choose the right fit, fabric and comfort

Buying clothes online may seem straightforward, but a great product photo doesn’t always tell the whole story. When shopping for clothes for women and men, unclear size charts, unsuitable fabric choices and exaggerated product claims can lead to disappointing purchases. This applies to menswear, womenswear, sportswear, casualwear and underwear.

Use this practical guide to compare T-shirts, sweatshirts, hoodies, jackets, polo shirts, boxer shorts, briefs and thongs based on features you can check. That way, you can find clothes that suit how you’ll wear them, your size and your laundry routine.

Common pitfalls when buying clothes online

1. Relying on the size letter alone

An S, M or XL doesn’t mean the same thing for every brand. A slim-fit T-shirt will fit differently from a relaxed-fit style. International size labels such as US, UK and EU can also cause confusion.

So, check:

  • chest, waist and hip measurements in centimetres;
  • the stated fit;
  • sleeve or garment length;
  • the size chart for the specific product;
  • any notes such as ‘generous fit’ or ‘true to size’.

For example, the adidas Trefoil Essentials Crew Sweatshirt lists a chest width of 48 cm for size S. That gives you more to go on than the letter S alone.

2. Assuming ‘cotton’ means 100% natural fibres

Cotton clothing often feels comfortable, but the label may show a blend. A sweatshirt, for example, may contain cotton and polyester, while underwear often includes elastane for stretch.

Always check:

  • the percentage of cotton;
  • whether it contains polyester, modal, nylon or elastane;
  • the fabric weight, if stated;
  • whether the fabric is designed for warmth, ventilation or freedom of movement.

According to the product information, the CAT Trademark Tee is made from 100% ring-spun cotton. The adidas sweatshirt is made from 70% cotton and 30% recycled polyester. Both are cotton clothing, but they won’t feel or wear in the same way.

3. Reading marketing claims without context

Terms such as ‘waterproof’, ‘sustainable’, ‘breathable’ and ‘moisture-wicking’ need to be considered in context. According to Nike’s product information, the Team Park 20 Hoodie features Dri-FIT technology for moisture management. This is a brand claim about how the fabric works, not a general guarantee for every use or sporting activity.

When choosing sustainable clothing, it’s also important to check the fabric composition. A percentage of recycled polyester or regenerative cotton tells you something about the material, but not necessarily about the garment’s overall lifespan, production or recyclability.

The key specifications to compare

Fit and ease of movement

For casual clothing, regular and relaxed fits are usually suitable if you want room around the chest, shoulders and waist. A slim fit sits closer to the body, so it’s important to measure carefully.

For sportswear, ease of movement, cuffs and seam construction matter more than appearance alone. A hoodie with ribbed cuffs and an adjustable hood can be practical for training or everyday wear. Just check that the fabric and care instructions suit how often you plan to wash it.

Fabric and warmth

A fleece lining will generally retain more warmth than lightweight jersey. According to its product description, the U.S. Polo Assn. sweatshirt has a fleece lining, a hood, a kangaroo pocket and ribbed cuffs and hem. This makes this style a good option for layering and everyday wear in cooler weather.

For a T-shirt, 100% cotton can feel comfortable for casual wear. According to the product information, The North Face Men T-Shirt NF0A8E4E is made from 160 gsm cotton and has a relaxed fit. A polo shirt, such as the Levi’s Men’s Polo, is also made from 100% cotton according to its product specifications.

Care and expected lifespan

A garment’s lifespan depends not only on the brand, but also on how you wash, dry and wear it. Pay particular attention to:

  • the maximum wash temperature;
  • whether it can go in the tumble dryer;
  • using a mild detergent;
  • washing with similar colours;
  • ironing at the correct temperature;
  • instructions for prints, logos and water-repellent finishes.

A garment that can’t go in the tumble dryer takes more time to care for day to day. Some jackets may need their water-repellent finish reactivated or maintained, as indicated on the care label. Always follow the label inside the garment, as product details may vary between versions.

Frequently asked questions about clothes for women and men

How do I work out my clothing size when ordering online?

Measure your chest, waist and hips with a flexible tape measure, then compare those measurements with the size chart on the product page. Keep the fit in mind too. A relaxed-fit T-shirt, such as the The North Face style mentioned above, gives you more room than a slim-fit design. If you’re unsure, the size chart for the specific product is more useful than your usual size in another brand.

Which fabric is best for everyday wear?

It depends on the garment and your preferences. Cotton is a popular fabric for T-shirts and polo shirts. A cotton-polyester blend may dry faster or hold its shape better, while elastane adds stretch to boxer shorts, briefs and thongs. Always check the exact percentages and the care label.

How can I make my clothes last longer?

Wash at the lowest suitable temperature, use a mild detergent and sort dark colours. Turn printed garments inside out and avoid tumble-drying them if the care label says so. For jackets with a water-repellent finish, follow the specific care instructions. This helps reduce unnecessary wear and keeps the fit looking good for longer.
