We want to create timeless garments; beautiful, yet ethical. It’s about starting a positive change,

a little fashion revolution.

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

Reshaping the way we perceive sustainable fashion, COSSAC encompasses the lifestyle, vision and values of founder Agata Natalia Kozak.

Our mission is to deliver timeless quality garments that are carefully made while respecting the value and rights of everyone contribution along the way. We promote transparency, manufacture sustainably and thrive on community.

Each season, a made-to-order capsule wardrobe collection is launched, offering a versatile selection of consciously designed contemporary garments that celebrate female body with a timeless ease. 

Committed to the slow fashion movement we provide women with simple yet daring pieces to complement their mindful lifestyle & creative freedom.
