Degas' fame and the value of his pictures continue to climb. As the decade progresses, he moves further away from the naturalism of earlier years; colors become more strident and spaces more contained, while details and figures become less numerous. Notable works of this period include several pictures of milliners, a pastel suite of bathers, and a series of frieze-format dance class pictures. "Green Dancers," c. 1885 1882 Opening of the seventh Impressionist exhibition. Degas chooses not to participate. "Dancers in Blue," c.1882-90    1886 May: The eighth and last Impressionist exhibition opens. Degas shows a series of pastels depicting women bathing or attending to their toilette. Offended by the ungainly figures and their shabby surroundings, many critics assume they are prostitutes; some commend Degas' unsentimental approach to the nude. 1887 Paris Opéra dancer, Rosita Mauri, is said to have posed for Degas --"Portrait of a Woman" may be a picture of her. "Portrait of a Woman," 1887 1888-1889 Writes a series of sonnets admired by the poet Mallarmé; one is dedicated to his friend, the ballerina Marie Sanlaville. "Mlle Sanlaville," c.1886
