Brand Story

ADDITION is a sustainable apparel brand offering essential, high-quality products for powerful, independent & conscious people. Founded in 2020 by us, glore Karoviertel – a concept store for sustainable fashion, ADDITION grew from our goal of completing our product range and of expressing ourselves through cuts, colours and patterns. Our aim is to work together, to cooperate and to share skills. Because together, we are the best team. ADDITION is a plus for our selection, a plus for your life. So now it is your turn, add sustainable apparel to your wardrobe – ADD SOMETHING BETTER!

Your Conscious Choice.

When you choose our eco brand partner, you help make the world more sustainable.

Brand Transparency

Who answered our brand transparency questions?

Wiebke Clef – CEO at ADDITION Sustainable Apparel.

Fair Trade


How do you ensure "Fair Trade" manufacturing? If your manufacturing or the manufacturing company you work with is certified, please list these certifications.

For us it’s super important working as closely as possible with the companies we are cooperating with. We follow every step of our products starting with the design and creation and ending up with the production under fair working conditions and highest social standards in Eastern Europe and Hamburg, Germany. Our focus is a totally traceable supply chain. We always want to make sure no one is harmed for any step of our production. Over the past years we’ve learned that transparency is a key part of our work - that’s something you should always add!

Social Justice


How do you ensure "Social Justice" with your internal and external corporate environment?

As a small team we are very happy to work together with other small companies, that we have known for many years. We trust each other and share our philosophy of making things better. If you only work with people sharing the same claim and values, there is no place

Organic Material


Which "Organic Material" do you work with? What makes this material sustainable? And what makes it better compared to conventional material?

We only use eco-friendly, high-quality materials that last for a lifetime. Our shoes are made of leather from organic cows, a by-product from the food industry. The leather we use is tanned with herbal substances, without the use of harmful chemicals that are often used and cause massive environmental pollution. Our fashion collection is made out of organic cotton, and other organic materials. Keeping our ecological footprint as low as possible and having a short supply chain are our main claims.

Eco/Tech Material

Which "Eco/Tech Material" do you work with? What makes this material sustainable? And what makes it better compared to conventional material?


Local Production


Where and why are your products manufactured "locally"?

Our fashion collection is made in Hamburg. We love the direct contact to the small tailor's shop and the short distances between them and our head office.

Give Back

Charity Social Integration

What organization do you donate to? Why is it important for your brand to "Give Back"?

We are a team of independent women, who always support each other and we always try to implement our ideas. We know this is a major privilege. We donate 3% of each sale to Femnet e.V. - an association that fights for women’s rights in the global clothing industry
