Why let yourself be tempted by huge discounts and fast passing trends when you have sustainable basics that will last a lifetime? Upgrade your wardrobe with some timeless basics and you'll always look stylish! At COSH! we give you some tips on what you should pay attention to when buying the right basics and we will list our favorite, sustainable basic brands so that you can enjoy them even longer!

What should you pay attention to when buying basics?

If you're looking for a new timeless and quality piece that is easy to combine with the rest of your wardrobe, you've come to the right place! At COSH! we give you tips on what to look out for when purchasing a new basic item.


A good, durable basic distinguishes itself from fast fashion brands by a good fit. Is the T-shirt too short or too long? Is the hood of that cool hoodie comfortable? But it also has everything to do with preferences of your personal style. Do you prefer a tight or wide T-shirt? Is the length of that jacket suitable for your body? Do you like a more basic fit or can it be a little more edgy? Ask yourself a number of questions that are important to you, so you can make a conscious choice for a new purchase.


When you buy a new basic garment, you naturally want it to fit so well that you never want to take it off again. Therefore, pay attention to comfort with a basic item. Is it a soft fabric that feels nice on my skin? Is the fit good enough for me to move around effortlessly? By asking yourself these questions before you buy a new piece of clothing, you increase the chance that you’ll wear it more often and with more pleasure!

Sustainable materials

Do you want to make a timeless and an ecological purchase? An important aspect in the field of sustainability is the material. Many basics are made from 100% natural materials, which are often better for people and the environment. Natural materials often feel nicer on the skin and fabrics made from 100% the same raw material are much easier to recycle than fabrics with a combination. You can also check whether a basic garment is made of, for example, organic certified cotton, mulesing-free wool or Tencel.

Locally/fairly made

Do you want to tick all the boxes when buying a sustainable basic item? Then investigate whether the brand produces the garments in a fair and/or local way. A garment that is produced in the Netherlands or Europe, for example, has to travel a shorter distance in terms of transport (so more sustainable!). But a garment produced outside Europe can also be made completely sustainably. Always check whether the brand ever visits the factory and/or whether they have quality marks. This way you can assume that your garment has been produced in a safe way and for a fair wage.

At COSH! we realize that this research can sometimes be a difficult, confusing and time consuming task. Could you use some help with this? Then take a look at the COSH! brand checker, where we have already researched more than 400 brands for sustainability with our own research team! This makes it easier for you to make a sustainable choice with your next purchase.
