Sustainable materials

Good for people and good for the planet

We strive to use more sustainable materials for every collection we make. Nearly all of the fabrics that we use are certified. You will find these labels on our products. We have an active policy to ban hazardous chemicals from our supply chain. King Louie also signed the Amsterdam Green Deal Circular Textile in 2021, a fashion alliance to produce fully circular clothes.

The production of clothes has a big impact on the environment. Because of the use of chemicals, energy, farmland and water, to name a few examples. We do our best to work with sustainable, certified materials as much as possible, in order to reduce our ecological footprint. By now, 77% of our collection is made of sustainable materials. We strive to keep increasing this percentage every season.



We believe that it’s important to burden the environment as little as possible with the production of our clothes. That’s why 70% of all the materials we use are certified. You can check these labels with our products.

The Global Organic Textile Standard (GOTS) is an international standard for organic textile.

The Organic Content Standard (OCS) applies to non-food products that contain 95-100% organic material. The standard checks how much organic material there is in the final product and inspects the route that the materials have taken from source to product.

EcoVero (officially LENZING™ ECOVERO™) is the sustainable version of viscose and is produced by the Austrian company Lenzing. LENZING™ ECOVERO™ fibers are certified with the EU Ecolabel. The look and feel of this fabric are similar to the materials Tencel and Lyocell. Unlike the production of viscose, the production of EcoVero takes place in the most environmentally friendly way possible.

We are proud Members of Better Cotton. Better Cotton trains farmers to use water efficiently, care for the health of the soil and natural habitats, reduce use of the most harmful chemicals and implement the principles of decent work.

King Louie is committed to sourcing 100% of our cotton as ‘more sustainable cotton’ by 2025. ‘More sustainable cotton’ includes GOTS certified cotton, OCS certified cotton, organic cotton and Better Cotton.

*Better Cotton is sourced via a chain of custody model called mass balance. This means that Better Cotton is not physically traceable to end products, however, Better Cotton Farmers benefit from the demand for Better Cotton in equivalent volumes to those we ‘source.’

Leather Working Group (LWG) is an organization focused on the environmental impact of leather production. In order to become LWG certified, manufacturers must implement special programs for energy use and wastewater. The leather used by King Louie is Gold Rated (the highest classification).

Global Recycled Standard guarantees the fabric consists of at least 20% of recycled content. The GRS certification verifies the recycled content and the socially responsible and environmentally friendly production practices. 

No dangerous chemicals

We have an active policy to ban dangerous chemicals from our whole chain. REACH (Registration, Evaluation, Authorization and restriction of Chemical substances) and POP (Persistent organic pollutant substances) are European laws, describing the limits that companies must comply with, with regard to chemical substances. This has resulted in a RSL (Restricted Substances List), which is a requirement for all of our manufacturers. In many cases, our RSL is stricter than many legal requirements. The independent and global Bureau VERITAS does spot checks to make sure our suppliers are complying with the RSL requirements.

We also work with a lot of companies that meet the criteria of OEKO-TEX, a test and certification system for textiles. The standard is focused on limited the use of hazardous substances in relation to the health of end users.

Animal welfare


We do not accept poor treatment of animals. We never use angora, down, fur and exotic skins in our collections.

We do not use a lot of animal materials (silk, leather and wool (blends)) in our collection. Only about 5% of our products are made with animal materials.

We require guarantees about the source of our materials and we prefer to work with a standard that guarantees good conditions for animals and humans. The leather used by King Louie is Leather Working Group certified. For our wool, we’re working very hard to meet the criteria. We will continue to make every effort.


Our ambition is a contribution of 5-10% of the post-consumer recycled (PCT's) yarns in 2025.

Circular production


In 2021, King Louie has signed the Amsterdam Green Deal Circular Textile, a fashion alliance to make fully circular clothes. We occupy a seat in the Circular Fashion Innovation Lab (CFIL). The first circular clothes, made with yarn of post-consumer waste, were expected in 2022. It turns out that we need some more time. Developing this innovative supply chain is very complicated and complex. Our ambition is a contribution of 5-10% of the post-consumer recycled (PCT's) yarns in 2025.

Residual materials

During clothing production, there are often pieces of fabric leftover (also referred to as 'deadstock'). We get those too. In order to avoid waste as much as possible, we choose to use these residual materials instead of throwing them out. We sell the clothing made of these leftover pieces of fabric as the 'Renewed collection’. The Renewed collection offers new models in fabrics and prints of previous collections. This way, we combine 'old' and new. We can offer these items at a discounted price: no new materials are used to make these products.


Returns, reconditioning and remnants

Returns and reconditioning

Returned clothes are usually added back to the stock. If an item of clothing is returned because it has a light stain, for example, it will be reconditioned first. This means that the item will be put up and cleaned, so that it can be returned to the stock after. This is done at our warehouse. If an item of clothing really cannot be fixed, it will be sold for a reduced price at the King Louie stall at the Noordermarkt in Amsterdam.

Fortunately, only a very small percentage of our returns are rejected. On average, this percentage is between 1 and 2%.




Items that we cannot sell in our stores and online shop are never destroyed. These items go to Batavia Stad Fashion Outlet, Otrium or the Noordermarkt.

Some of the items that still have a lot of stock including all sizes at the end of the season (when the sale starts) go to our King Louie store in Batavia Stad Fashion Outlet.

Some of our remnants are also sold on the Noordermarkt and at Otrium. Otrium is an online outlet where brands can sell their overstock. So you’ll often find items from previous collections here. They are usually one season behind.

If there are still leftovers after all of this, these remnants will be donated. For example, our outlet in Batavia Stad sent a shipment of winter items to Ukraine in 2021. King Louie also made a donation to the Salvation Army in December 2021, and we have also donated a full shipment of clothes to refugees in Greece (Lesbos) in the past. 


King Louie Classics


Aside from our semi-annual collections, King Louie also has a 'Classic collection'. This is a fixed selection with timeless models that we sell every season. Since these items have been a part of our range for years, the quality and fit are perfect. The Classics offers various models and colors, so every woman will be able to find the perfect item.

The Classics collection consists of a basic selection of models and colors that return every season. These items are timeless and combine perfectly with King Louie items from previous collections (or items from other brands), which means they don’t go on sale. Furthermore, a few colors are added that fit the current season, and these items do go on sale at the end of the season. 


Fabrics and product care


In order to enjoy your clothes as long as possible, it’s important to take good care of them. Would you like to know more about the (sustainable) fabrics that we use, and how you can keep them looking good for a long time? 


Dierlijke materialen in onze collecties


Het gebruik van dierlijke materialen (zijde, leer en wol(blends)) binnen onze collectie is klein.  Gemiddeld 5% (SS22 1%, AW21 8%) van onze producten bevat dierlijke materialen.


Dit is de geschoren vacht van een schaap. Wol is op zichzelf een natuurlijke vezel, wol gaat lang mee en is zelfreinigend. Veel van onze producten bevatten slechts een klein percentage wol om de vintage uitstraling te krijgen. 


Dit is de geschoren vacht van de angorageit. Het is een vezel die lang meegaat, sterk is en bijzonders slijtvast. Het mohair in onze producten is afkomstig uit Zuid-Afrika.


Dit is de geschoren vacht van de alpaca. Alpaca wol is een prachtig duurzaam product welke zonder dierenleed gewonnen wordt en lang meegaat. Het alpaca wol in onze producten is afkomstig uit Peru. 


Het leer dat gebruikt wordt voor onze producten is altijd een restproduct van de vleesindustrie. We willen het gebruik van leer beperken, op dit moment is 0,05% van onze collectie van leer. Als we gebruik maken van leer, is het een voorwaarde dat we voor de duurzame variant gaan. In dit geval Leather Working Group Certified: 75% van het leer dat wij gebruiken valt onder deze standaard.
