In 2014, after working for both high end and high street labels and with some distinguished designers for LFW, and witnessing fast fashion’s destructive influence in the industry she loves, Agatka Kosak decided to launch her label, COSSAC.
Designed in London and made in Europe, COSSAC promotes the minimalistic concept of the capsule wardrobe, and offers a curated selection of contemporary threads and redefined basics with a sassy edge. Sustainably designed and ethically produced, each quality garment is intended to be transeasonal, with the aim of minimising wastefulness and maximising usefulness.
An emerging eco fashion brand, COSSAC — and in fact, Agatka herself — has already gained support from conscious fashion advocates and received mainstream coverage from publications including Glamour (Germany), C-Heads Magazine, Self Control Mag, Nylon, Flanelle Magazine and Superior Magazine.
In the words of COSSAC:
"We are committed to slow fashion and sustainable design. Transparency, sustainability and social well-being is at the core of our business. We reject the mainstream practices of fast fashion that produces cheap, low-quality and disposable trend items by exploiting workers. COSSAC exists to offer women design-led conscious fashion to help drive awareness of the negative social and environmental impacts of the fashion industry and make it easy for women to make better choices.
We think sustainable fashion that no one wants to buy or wear is 100% wasteful. That’s why we design clothing that customers actually want to wear. The designs are contemporary with a sassy twist making them relevant to the modern woman. The silhouette celebrates the feminine form but is classic enough so that our garments are worn and cherished beyond the current season. Our production runs are limited to minimise waste and deadstock."
COSSAC use sustainable materials in our collections such as organic cotton, Tencel and modal. In selecting the fabrics, the team place a lot of importance on how it is produced and the extent of its impact on the environment, such as how much water and toxic chemicals is used. All fabrics selected are ethically-sourced, organic or have low environmental impact.
COSSAC work exclusively with small factories with whom they have built close relationships with. All production is carried out in Europe, in Portugal and Turkey in ISO and GOTS-certified factories. This reduces time, cost and eco footprint of transporting the garments.
The team also believe in supply chain transparency as ethical treatment of workers is as important to us as our environmental impact. They use accredited factories because they care about the people who help make our clothes. Every supplier and factory we work with holds certificates assuring COSSAC'S high work standards and expectations are being followed. The team regularly travel to factory partners to make sure the processes are overseen and are compliant with ethical production standards.
