Ensuring fair and safe work conditions has first priority at Studio Ōsoi. We partner exclusively with factories that prioritize worker welfare and environmental sustainability. This means that every piece we produce is crafted with care, under conditions that respect the rights and well-being of workers. We strive to foster long-term relationships with our partners, based on mutual respect and shared values.



We believe in creating products that are not only beautiful but also built to last. Our meticulous attention to detail ensures that each item meets our high standards.


We maintain open communication with our customers about our production processes, sourcing, and the impact of our operations.


We are committed to minimizing our environmental footprint through responsible sourcing, efficient production methods, and sustainable materials.


At Studio Ōsoi, we craft each piece with care to achieve timeless designs with unique twists. We prioritize quality materials, sourcing the best available options such as merino, cashmere, Ecovero, micromodal, and linen, as well as select deadstock materials whenever possible. Our commitment extends to ethical and responsible production, partnering exclusively with factories that prioritise worker welfare and environmental sustainability.




All our pieces evolve from a long process of creation. We produce several prototypes per style that we test, wear and adjust to the last detail having the best possible outcome in mind. We focus on timeless design with an extra twist.  


All materials are chosen very carefully, always trying to find the best solution for each product. We prefer to work with deadstock, recycled and organic materials and avoid synthetic fibers where possible.


To ensure all our pieces are ethically and responsibly made, we choose to only work with factories that care about their workers and our planet. Before we start working with new manufacturers, we make sure to visit them, if circumstances allow for it. That way we can build personal and trustworthy relationships with our workers.
