About Dear Denier

Dear Denier is your sustainable choice within hosiery. Through the use of sustainable materials such as recycled nylon, traceable natural fibres, and even leftovers from other companies’ production processes, Dear Denier offer durable and eco-friendly hosiery.


The hosiery is for every woman who not only cares for herself and the ones she holds dear, but also for the future to come. Dear Denier combines design with state-of-the-art production in sustainable factories in Italy.


Dear Denier was founded in 2012 by Danish Katrine Drost Lewinsky, and the company has been growing ever since. Recently Katrine’s husband, Frederik Lewinsky, quit his job in the Danish financial industry in order to join the visionary brand and help make their family dream come true: To deliver sustainable and high-quality tights and socks for the modern conscious woman.

Brand Ethos

For Dear Denier, it’s all about caring. Caring for yourself, the ones you hold dear, and the future to come. Dear Denier’s sustainability manifesto prescribes pushing for change through caring and owning up to the responsibility as a fashion accessories maker. That is why they are a Born Sustainable brand in our world.

Brand sustainability

Dear Denier are on a mission to design and produce socks and stockings for modern women in an unconventional way by challenging the fashion industry’s bad habits and ingrained patterns when it comes to material selection and manufacturing. They are all about taking full ownership of the value chain and creating a transparent supplier setup to be close with the product all the way from design to materials to packaging. 

The fundaments of Dear Denier are: 

- Sustainable hosiery
- Recycled and low impact materials
- Zero-waste production and renewable energy
- Innovative recycling initiatives


As the only company in Denmark, among very few hosiery brands in the world, Dear Denier uses recycled nylon and fully traceable natural fibres when producing socks and tights. All of this happens exclusively in Italy at zero-waste factories that focus on minimizing environmental impact by for example cleaning wastewater and air, waste sorting, using solar power and other renewables, and minimizing the use of chemistry. By using a new technology that makes it possible to utilize waste nylon and make it into new nylon, they see savings of approx. 80% in CO2 emissions and 90% in water consumption. 

Raw Materials


All raw materials such as Egyptian cotton, Italian silk and cashmere come from Italian suppliers who have certificates such as EU Ecolabel, GOTS, Global Recycle Standard, ISO 9001, OHSAS 18001, OEKO-TEX, DETOX, HIGG Index and even the zero-waste factories are OECO-TEX-certified.


Dyeing facilities

The dyeing facilities are also zero-waste facilities, that filter and clean all of the wastewater from the dyeing process before discharging the water back into the municipal sewage treatment plants.



Lastly, Dear Denier packaging is FSC-certified which ensures that the packaging materials are made from responsibly managed forests that provide environmental, social and economic benefits. Even more, the packaging can be reused for a different purpose. All hosiery comes in a box instead of the traditional envelope and the box can be used for storage for whatever fits inside such as jewellery, tights or the like.

Product Lifecycle


The Design Phase is a crucial part of determining a product’s sustainable capabilities. We’ve chosen to highlight a few genius steps that enable a sustainable product right from the beginning.

    Material & Material Extraction

    The materials used for a certain product and how these materials come to life are of crucial importance to the sustainable capabilities we seek in products.

      Transportation of Materials

      This step relates to the transportation of the raw materials from when they are first obtained (harvested etc.) to the production site. Obviously, the closer to the production site, the better.


        Obviously, the production of a certain product has an impact on the overall level of sustainability. Luckily, many manufacturers have now taken steps towards more sustainable production methods.


          How a brand chooses to package its products will have a significant influence of the carbon impact from packaging and transportation.


            This step relates to the distribution of products when they have been produced. Obviously, the closer to the brand’s warehouse, the better.


              How you choose to use and take care of a product has a bigger impact than you think. Just think about how much longer a shirt lasts if it has been washed in the right way.

                End of life

                At this step, there is no way out and we have to find some way of discarding our product. How we discard a product will significantly influence the opportunity of reusing materials used.
