Paul Poiret called this item a "kimono coat." The pieces constructed the coat were cut straight. Poiret introduced loose-fitting silhouette coats like this example at the same time as the "Lola Montez" dress in 1906 and the directoire dresses in 1907 and subsequent years. The "Lola Montez" and directoire dresses were one-piece dresses with a new silhouette having the support point at the shoulders instead of the waist.
The label shows the address of Poiret's house on Rue Pasquier, where he worked from 1906 to 1909.
