Callot Soeurs was a fashion design house opened in 1895 at 24, rue Taitbout in Paris, France. It was operated by the four Callot sisters: Marie Callot Gerber, Marthe Callot Bertrand, Regina Callot Tennyson-Chantrell and Joséphine Callot Crimont.
The eldest sister, Marie, was trained in dressmaking and they were all taught by their mother, a lacemaker. The sisters began working with antique laces and ribbons to enhance blouses and lingerie. Their success led to an expansion into other clothing and in 1914 they moved to larger premises on the Avenue Matignon.
Marie, the elder sister was in charge of design, having earlier worked for Raudnitz and Co., prominent Parisian dressmakers. The couturier Madeleine Vionnet was apprenticed at Callot upon her return to Paris. It was here that she refined her technique in couture. Callot Soeurs clothing was known for its exotic detail.
