Buying clothes online: how to choose comfortable clothing without a costly mistake

Buying clothes online is convenient, but a great product photo doesn’t always tell the whole story. A pair of trousers might fit differently than expected, a T-shirt might come up smaller, and a fabric description doesn’t mean much if you don’t know how the material feels to wear day to day.

Use this practical checklist to focus on the details that make the biggest difference: size, fit, material, intended use and care. You can compare menswear, womenswear, sportswear and casual clothing using verifiable product information rather than relying on marketing claims alone.

Three common pitfalls when buying clothes online

1. Relying on S, M, L or XL alone

Sizes vary by brand, collection and style. An XL in slim-fit trousers might fit differently from an XL in a relaxed-fit sweatshirt. So check a specific size chart or measurement. For example, the Adidas Trefoil Essentials Pants list a waist measurement of 91–96 cm for XL. That’s more useful than the size label alone.

2. Assuming “comfortable” means suitable for every situation

Cotton can feel pleasant, while polyester can be a good choice for sportswear during more intense activity. Fleece sweatpants are suitable for cold days or relaxing at home, but they’re not automatically right for a formal workplace. So consider the material, fit and intended use together.

3. Skipping the care instructions

A garment that can only be washed at a low temperature or can’t go in the tumble dryer needs more care. This affects both the cost of wearing it and how long it lasts. Check whether dark colours need to be washed separately and whether a printed design should not be ironed directly.

Which product details should you check?

Size and fit

Look out for the following details:

  • Body measurements: waist, chest, hips or inside leg.
  • Fit: slim fit, regular fit, straight leg or wide leg.
  • Stretch: 100% cotton and non-stretch denim feel different from a cotton blend with elastane.
  • Model’s measurements: useful as a guide, but no substitute for your own measurements.

According to the product information, the Adidas Adicolor Classics 3-Stripes Tee has a slim fit, a chest width of 48 cm in size M and is made from 100% cotton. If you prefer more room to move, look for a regular fit rather than relying on the chest measurement alone.

Size combinations are especially important with jeans. The Levi’s 501 jeans in size 32/32 have a straight-leg cut and an inside leg of 76.2 cm, according to the stated size chart. Also check whether the style contains stretch; this version is described as 100% cotton with no stretch.

Material and intended use

Material affects warmth, texture, moisture management and care, among other things:

  • Cotton: often chosen for T-shirts, polo shirts, blouses and casual clothing.
  • Polyester: widely used in sportswear and lightweight jackets.
  • Cotton blend: can offer a balance between comfort and easy care.
  • Fleece: suitable for extra warmth in sweatpants or sweatshirts.
  • Mesh or lightweight woven fabric: can work well for loungewear on warmer days.

The Nike Dri-FIT Park 20 Tee product description says the shirt is designed for sports and casual wear and has a regular fit. It attributes its technical performance to Nike’s Dri-FIT technology; treat this as a brand claim from the product information and also check the stated fabric composition. The details list 57% cotton and 43% polyester, while the general description also says 100% polyester. If the information is inconsistent, it’s a good idea to check the product page and care label before ordering.

Care and cost of use

Washing clothes less often, using a suitable temperature and air-drying can help them last longer. Always follow the care label for the specific item.

Examples from the product details:

  • The Adidas sweatpants are made from 70% cotton and 30% recycled polyester. The instructions say to wash cold on a delicate cycle and not to tumble dry.
  • The Urban Classics Fluffy Sweatpants are made from 70% cotton and 30% polyester. The product information recommends a cold wash and drying at a low temperature or on a washing line.
  • According to the description, the Levi’s 501 should be washed cold and turned inside out, with similar colours.

Also check what’s included in the delivery. A loungewear set contains a top and bottoms, but the fit and size can differ between the two pieces. The Purcotton sets list body height and separate sizes for the top and bottoms.

More ways to find the right pieces for your wardrobe

If you’re comparing clothes online, you can narrow down your choices further:

  • Menswear: check chest, waist and shoulder measurements, especially for polo shirts and shirts.
  • Womenswear: check the waist, hips and cut, such as a high-waisted or wide-leg style.
  • Sportswear: compare the fit, room to move and material with the activity you have in mind.
  • Loungewear: check whether the set contains two pieces and whether the top and bottoms sizes match your measurements.
  • Casual clothing: think about how easily each item can be styled. A black polo shirt, jeans, blouse or pair of chinos can work for several occasions.

The range includes items such as Adidas clothing, Levi’s jeans, a Nike sports T-shirt, Urban Classics clothing, blouses, chinos, sweatpants and T-shirts. Before you check out, view each item’s current availability, size, colour and returns policy.

Frequently asked questions about buying clothes online

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

Measure a garment that fits you well and compare its chest, waist or hip measurement with the size chart on the product page. Also check whether the fit is slim, regular, straight or wide leg. If you’re between sizes, choose based on how much room to move you want and the material.

How long do clothes bought online last?

It depends on the material, how often you wear them, friction and how you care for them. Follow the care label, avoid unnecessarily hot washes and only use a tumble dryer if the label allows it. Non-stretch denim may wear differently from a lightweight cotton blend, so compare more than just the brand or price.

Is buying clothes online cheaper than shopping in store?

Prices can be higher or lower depending on offers, delivery costs, return costs and whether your size is available. Always compare the total cost and check the product details. A bargain that doesn’t fit can still cost you extra money and time.
