COSSAC was created in 2014 by Agata Natalia Kozak with a simple idea: clothing should feel instinctive - for you, and for the planet.
We design elevated feminine essentials: simple shapes, refined details, instinctive silhouettes. Pieces that make getting dressed feel natural, not complicated.
We believe in slow-made design - small runs, responsible materials, conscious decisions. We create concise Capsule Collections: fewer pieces, designed to integrate effortlessly into your wardrobe.
We don’t chase seasons or trends. We create a wardrobe that lives with you - from weekday to weekend, from city to escape.
COSSAC exists for women who choose less and better, who invest in pieces that feel as good as they look.
Considered design. Elevated feminine simplicity. Made slowly, to be worn for years.
