Here, from the historical collection is Simplicity Costume Pattern # 9764. This is from the Civil War series and is an UNCUT Misses Crinoline (hoopskirt slip) and Petticoat Size 14 16 18 20.
WAIST from 28 inches to 34 inches! (You don't need to worry about the bust or hip measurement.)
This is the essential pattern for the undergarments that are needed to complete the historical look of the other Simplicity Civil War Era.
THIS IS JUST THE PATTERN!
The pattern and instructions are still factory folded. The envelope shows some wear and creases from storage.
