Why are certifications important? What do they mean?

We believe that it's incredibly important to ensure that fabrics carry certifications when consciously purchasing new clothing. This will tell you how sustainable a product really is : Are the materials organic? Is the product fair trade? To what standard?

Sustainable fashion and fair trade certification logos

At Zola, we felt Fashion Revolution Week was the perfect time to look into the basic sustainable certifications and share our knowledge with you. Here are some of the main ones you need to know about.

Certification's in our products.

Global Organic Textile Standard

This label, Global Organic Textile Standard (GOTS), means that a product is made of a minimum of 70% of organic fibres and that it meets the Soil Association’s standards. In this process, every step of the supply chain will be looked at, from harvesting through to production and labelling. The environmental management and social responsibility of the producer is also considered. Find out more here.

All of our products containing cotton whether it's a blend, such as our OEKO-TEX bamboo/ GOTS organic cotton t-shirts

or our full cotton products such as our GOTS organic cotton jumpsuits.

We even go as far as to stitch using GOTS organic cotton thread to ensure that every part of our product is regulated and natural. 

The OEKO-TEX 100 standard

This certification regulates the chemicals used to make yarns. It ensures that harmful chemicals and banned substances are not used in the production of such yarns as well as making sure that the cloth we use is certified as being free from harmful substances. You can find out more here

All of our bamboo products are OEKO-TEX certified, including the blended fabrics used for our GOTS organic cotton/ OEKO-TEX bamboo t-shirts.

Our bamboo shirts are also OEKO-TEX certified and the yarn is made using a closed loop system (this means that the chemicals used to produce the yarn, such as sodium hydroxide, are re-used over and over again). 

Other certifications to be aware of. 

The FAIRTRADE mark :

This has now become a rather common logo we see on many products, not only clothes. When it comes to fashion, this means that the cotton used for the piece of clothing was produced by a Fairtrade certified producer in a developing country. The Fairtrade standard aims to provide support for social, economic and environmental development for small scale producers organisation. Find out more here.


The Soil Association is he UK’s largest organic certification body.This charity was formed in 1946, to make a positive change and create a better world.They are in charge of setting out the next three labels we will discuss by verify a brand’s supply chain's impact on the environment. To do so, they look at criteria such as the use of harmful chemicals, safe working conditions, carbon footprints and many more. Find out more here.

Two Other Organic Standard Certifications

These last two labels, inform you of the amount of organic fibres in an item of clothing.

The first is the OCS 100 logo, used only for product which contain 95% or more organic material.

The second is the OCS OCS blended logo, used for products that contain 5% minimum of organic material blended with conventional or synthetic raw materials.

We sure hope this article was helpful and helps to make sure you shop responsively, keeping an eye out for these certifications.

You can be assured that at Zola Amour we do and always will only buy fabrics that carry trusted certifications!
