Founded by Polish sisters, “SIISTER SZN” is inspired by our roots in Eastern European fashion—where effortless style meets everyday comfort, and looking put-together never feels forced.
Through conversations with friends and women around us—each with diverse careers, lifestyles, and personal styles—we began to understand what so many felt was missing when shopping. Rather than following trends alone, we curate and offer high-quality women’s clothing that reflects what customers want to see more of.
The story behind SIISTER SZN is one of resilience, determination, and a passion for creating something meaningful.
From the age of 13, Iza has lived with a chronic illness that has presented ongoing challenges in maintaining a typical routine and navigating everyday life. As she completed her education and entered the working world, she realised that traditional career paths were not compatible with her health. Rather than allowing those challenges to define her future, they inspired her to build something of her own.
Driven by a vision of independence, creativity, and empowerment, Iza set out to create what is now SIISTER SZN. With the unwavering support of her family, that vision has become a reality.
SIISTER SZN is more than just a business—it's a community built on self-belief, resilience, and lifting one another up. We hope our journey inspires others to embrace their own path, whatever challenges they may face.
Welcome to the Siisterhood.
