Buying sustainable clothing online: how to choose materials, fit and usage wisely

Buying sustainable clothing online sounds straightforward, but product pages do not always tell the whole story. A green label, a well-known brand name or the term “breathable” says little on its own about whether a garment is suitable for your everyday needs. If you focus only on appearance or discounts, you could end up with clothing that fits poorly, quickly loses its shape or is unsuitable for the Dutch weather.

Pay particular attention to these three common pitfalls:

  • Vague sustainability claims: “responsibly produced” does not always state which material has been used or what proportion is organic or recycled.
  • Incomplete sizing information: a size such as M or 128 varies by brand and model. Without chest, waist or hip measurements, buying online remains a gamble.
  • Incorrect expectations about functionality: a waterproof outdoor jacket is not automatically suitable for intense activity. Check whether waterproofing, ventilation and care instructions are described clearly.

Which specifications should you check?

1. Material and certification

For organic cotton clothing, the difference between “cotton” and organic cotton matters. Check the material percentage and see whether a certification is mentioned. For example, the Urban Classics cropped rib top is described as a blend of 95% organic cotton and 5% elastane. For some versions, the product information also states that GOTS-certified organic cotton is used. Always check the information on the current product page, as the composition and design may vary by size or model.

A small amount of elastane can be practical for close-fitting clothing, such as a ladies’ cropped rib top. It gives the fabric stretch, but also requires careful washing and drying to help maintain the fit.

2. Fit, size and freedom of movement

For children’s clothing, it is better to use body measurements rather than relying solely on the age indication. For example, the Tommy Hilfiger ESSENTIAL SWEATSHIRT Kids Gender Inclusive Twilight Navy is available with size references such as EU 98, 104, 110 and 116. The corresponding chest, waist and hip measurements help you make a choice based on more than just age.

Also consider the intended use:

  • A sweatshirt can have a slightly looser fit for school and leisure.
  • Underwear should fit comfortably without feeling tight.
  • A jacket should leave room for a mid-layer.
  • A cropped top is shorter and usually works best with high-waisted trousers or a skirt.

3. Function and care

With a breathable hardshell jacket, terms such as “waterproof” and “breathable” are only useful when you also consider the construction, material and care instructions. The PELLIOT jackets are described in the product information as hardshells with a water-repellent laminate layer, mesh or technical fabric on the inside, and a nylon or polyester blend. The manufacturer also states that recycled material is used in the outer fabric.

These are product claims made by the manufacturer or seller, not independently verified performance figures. So check whether a hydrostatic head rating, breathability rating, taped seams or a clear usage classification is provided. If this information is missing, do not automatically assume the jacket will perform in prolonged heavy rain or on demanding mountain trips.

Care also affects how long clothing remains usable. Follow the care label, preferably use a mild detergent and avoid drying at high temperatures unless recommended. For example, according to the product information, an organic cotton hoodie can be washed at 30 °C and must not be tumble dried.

Frequently asked questions about buying sustainable clothing online

How can I check whether clothing is genuinely sustainable?

Look at the material composition, any certification, information about the origin and the care instructions. A general claim such as “environmentally friendly” is less informative than a statement such as 100% organic cotton or a specific proportion of recycled material. According to information provided by the manufacturer concerned, a product may have certain sustainability features; treat such claims as product information and check exactly what has been specified.

Is organic clothing more expensive to use?

Not necessarily. The purchase price is only one factor. A multipack, such as a 5-pack of organic boxer shorts, can be practical when you need several items. Wash clothing according to the label, avoid unnecessarily high temperatures and air-dry materials whenever possible. This helps to limit wear and energy consumption.

What should I look for in sustainable children’s clothing?

Choose a size based on body measurements, not age alone. Check whether the fit is gender-neutral if siblings want to share the garment, and look at the cuffs, seams and fastenings. A sweatshirt or hoodie made from organic cotton is useful as comfortable leisurewear, but it should also provide enough freedom of movement for school and play.
