Dress of the day: Jeanne Lanvin, Robe de style (1927). I love so many of Lanvin's designs it's hard to pick one, but I am particularly interested in her robes de style. This type of dress featured ankle-grazing length, simple lines, and often ornate decoration. It offered a wearable alternative to more daring flapper styles in the 192s and was a strong seller for Lanvin. This example was worn by Mrs. Charles Dewey of Chicago for her presentation at the Court of Saint James.
