Rosie Assoulin is a luxury women's fashion brand founded in 2013 by Brooklyn-born designer Rosie Assoulin. The brand emerged from the designer's lifelong passion for fashion, which began at age 13 when she started experimenting with fabric and design on her grandmother's sewing machine. After interning at prestigious houses like Oscar de la Renta and working at Lanvin in Paris under Alber Elbaz, Assoulin launched her eponymous label with a clear vision of creating sophisticated yet sensuous clothes that never sacrifice comfort. The brand is renowned for its sculptural designs that feature dramatic plays on volume while maintaining wearability. Assoulin's aesthetic strikes a balance between the romantically fantastical and reliably practical, offering women clothes that express their complexity and individuality. All pieces are made in New York using fabrics sourced from Italy, reflecting the designer's commitment to quality craftsmanship and supporting local production. The brand has garnered significant attention, dressing celebrities like Zendaya, Rihanna, and Katy Perry, and establishing itself as a go-to for refined, fashion-forward women.
