The subject of this elegant full-length portrait is Chase's oldest child with his wife Alice Bremond Gerson, Alice Dieudonnée, (b. 1887), nicknamed “Cosy.” Chase often used his family and friends as models for his paintings, and his wife and children were often recognized in public as the subjects in his work. As Alice grew older, she gradually replaced her mother and namesake as a favorite model, perhaps in part because she increasingly resembled her mother at the age when she met the artist.
