Extant wrappers range in design and material from conservative to lavishly extrovert and colorful. Some wrappers were made from exactly the same fabrics as regular dresses, cut like a dress in the back and sides. With the help of a belt such wrappers could be made to look just like a regular dress. Others were made from paisleys and other "loud" fabrics, with a bold contrasting panel or trim in the front, or with a cut that was loose all the way around; these cannot be made to look like regular dresses.
The original wrappers this pattern is based on were cut in the back as a regular dress and only the loose front panel mark them as wrappers. This kind of "wrapper dress" can be found in styles that date them from 1830-1900.
