Founded by Osi Ettlinger, OSIS Studio is dedicated to redefining sophistication for every woman, at every stage of life. With over two decades in fashion, Osi’s designs focus on creating timeless pieces that transcend trends and remain relevant for years to come. At OSIS, we believe in sustainability as a core value. Every fabric—cashmere, wool, cotton, silk—is carefully sourced for its quality and durability, ensuring each piece is an investment in a wardrobe that lasts. Our mission is to offer clothing that not only stands the test of time but also empowers women to feel confident and elegant, no matter their age.

OSIS is about embracing your individuality—wearing what feels true to you, at any point in your life. Inspired by the energy of Los Angeles, OSIS combines strong yet soft, classic yet contemporary designs in a color palette that reflects the city’s vibrant spirit. OSIS is more than fashion—it’s a philosophy of intentional dressing, built to elevate every woman’s confidence and style.
