She is Sunday is a brand created from love and passion

WHO ARE THE FOUNDERS?

They are a mother-daughter duo: Karolina Miko, a creative designer, and Mariola Rutkowska, owner of Atelier Szycie na Miarę. We are not a corporation—we create a close community of women who love fashion, comfort, and beautiful details. Our designs are made in Warsaw’s Powiśle district, where we ensure the quality and unique style of each piece.

OUR PHILOSOPHY

The Sunday girl is a dreamer and traveler who celebrates free moments as if every day were Sunday. We are inspired by holiday moments, California sunshine, Italian coasts, the French Riviera, and the gentle vintage of the 70s. We create clothes that carry lightness, harmony, and a desire to explore the world.

  • Dopamine and Energy

    The colors of the collection bring lightness and good energy, evoking the most beautiful memories. We designed the cuts with modern travelers in mind, who combine comfort with elegance – for a walk in the park or a journey to the other side of the world. Every day can be an adventure.

  • Craftsmanship and locality

    Our clothes are made in small sewing workshops in Łódź, where we support Polish craftsmanship and local creators. We are a family brand, and passion and precision passed down from generation to generation create collections that combine modernity with Polish tradition. Every design is the result of the work of people who put their heart into it.

  • Caring for the planet

    We follow the principles of sustainable development. We use eco-friendly plastic bags and natural materials such as cotton, wool, and viscose. We care about your comfort and the future of the planet by creating clothes from environmentally friendly fabrics. Every stage of production is designed to minimize the impact on nature while preserving the beauty and quality of our products.
