Woman with a Pearl Necklace in a Loge (or Lydia in a Loge) is an 1879 painting by American artist Mary Cassatt.
The Philadelphia Museum of Art acquired the painting in 1978 from the bequest of Charlotte Dorrance Wright.
The style in which it was painted and the depiction of shifting light and color was influenced by Impressionism.
This painting shows a view of the modern woman and is similar in style to Degas.
