COSSAC is reshaping the way we perceive sustainable fashion.

Each season, we deliver a small capsule collection that embraces modern simplicity but always with a fresh twist. 

Designed in London and ethically produced in Europe, COSSAC celebrates human connections. Our mission is to deliver timeless quality garments that are sustainably made while respecting the value of each contribution along the way.
We promote transparency, manufacture sustainably and thrive on community.
We trust in the power of people to inspire and influence each other, all for the purpose of creating positive change in the way we live and consume fashion.

We believe fashion is even more beautiful when it’s produced ethically. Join us on our journey x
